The "Send to HyperFrames" authoring guide is an internal contract for the Claude
Design import flow, delivered exclusively by the get-send-to-hyperframes-guide MCP
tool (raw server-side fetch of the .md, returned as tool-result data). The llms.txt /
web_search discovery path it was published for is no longer used. Drop it from
docs.json so it stops appearing in the public product docs nav + llms.txt; keep the
.md file at its path (the tool's raw fetch URL depends on it) and the redirect note in
claude-design-hyperframes.md (points at the raw URL, not the docs page). Orphan guide
files build cleanly here (claude-design-hyperframes.md already is one).

## What
Refactor distributed planning around one shared local execution-plan builder:
- `buildLocalExecutionPlan()` now owns compile/probe/extract/audio/freeze.
- Legacy `plan()` remains a deprecated v1 transport wrapper.
- Plan v2 calls the shared builder directly and publishes through the existing manifest/CAS contract.
- Add neutral `createPlanV2FromExecutionPlan()`, `publishPlanV2FromExecutionPlan()`, `getPlanV2ExecutionPlanHash()`, and `PLAN_PROTOCOL_V1` names.
- Retain deprecated v1-named exports and wire aliases.
- Recommend explicit Plan v2 opt-in for new producer, Lambda, and Cloud Run integrations.
## Why
Plan v2 previously looked like it invoked a v1 planner even though v1 and v2 share the same frozen local execution representation. This removes that migration-era coupling while preserving the public minor-version compatibility contract.
## How
The shared builder returns neutral internal execution-plan fields. The v1 wrapper maps those fields back to the existing `PlanResult`; the v2 publisher consumes them directly.
Compatibility is intentional and covered by exact shape tests:
- omitted `planProtocol` still serializes/selects `"v1"`;
- v1 layouts, descriptor-less decoding, event unions, workflow branches, and exports remain;
- the v1 descriptor JSON is byte-identical and `CURRENT_PLAN_PROTOCOL` is an identity-preserving alias;
- v2 manifest bytes, key order, hash framing, and `sourcePlanV1Hash` wire key remain unchanged;
- no enumerable neutral hash field was added to manifests or returned result objects;
- v1/v2 result objects, cloud event payloads, and SDK handle key sets remain unchanged.
## Test plan
- Focused Plan v1/v2/protocol/export/size compatibility: 141 passed
- `@hyperframes/core`: 1,419 passed
- `@hyperframes/producer` unit lane: 990 passed
- `@hyperframes/aws-lambda`: 140 passed
- `@hyperframes/gcp-cloud-run`: 101 passed
- Producer, Lambda, and Cloud Run typechecks
- Repository-wide lint, format check, workspace/package-subpath checks
- Full workspace build
- `git diff --check`
- [x] Unit tests added/updated
- [ ] Manual testing performed
- [x] Documentation updated (if applicable)
* refactor(lint): route asset-src skips through a shared isUnresolvedAssetPlaceholder predicate
Follow-up to the templating-token fix. The __UPPER__ + templating-token skip was
copy-pasted across the asset-src sites and had drifted: two non-lint sites carried only
the __UPPER__ half, and htmlCompiler's comment still claimed it "matches lint's skip"
after lint's skip became a superset. Extract one isUnresolvedAssetPlaceholder(rawSrc) in
@hyperframes/parsers/asset-resolution (both placeholder shapes, checked on the raw value)
and route every site through it: the four project.ts lint sites, hevcPreviewLint, and the
two previously-missed post-substitution sites (studio-server mediaCodecMap, producer
htmlCompiler). Remote/inline handling stays per-site (audio uses a narrower check).
Behavior-preserving for the lint sites (full suite green); the two non-lint sites are
post-substitution so they don't false-positive today, but now share one definition and
can't drift again. Adds unit tests for the predicate.

* docs(parsers): refresh hasUnresolvedTemplatingToken aside for the shared predicate
The parenthetical said the __UPPER__ shape keeps its own inline check at each call
site; this branch folded it into isUnresolvedAssetPlaceholder, so point there instead.

- parseFrameRate now rejects malformed ratios (e.g. "30/", "30/0") instead of NaN.
- Add "--" before file paths so names starting with "-" are not parsed as options.
- cICP PNG chunk no longer returns before IHDR supplies width and height.
- Add regression tests for option injection, frame rates, and cICP ordering.
- Problem: @hyperframes/studio package docs showed bun run dev without the
localhost URL contributors need after #2901 fixed contributing.mdx only.
- Fix: note that the studio dev server listens on localhost:5190 per
packages/studio/vite.config.ts server.port.
- Verification: preflight_ship.py + read vite.config.ts; bun run format:check.
- Problem: setup guide pointed contributors to localhost:3000 after bun run dev.
- Fix: use localhost:5190 to match packages/studio/vite.config.ts server.port.
- Verification: preflight_ship.py + read vite.config.ts server.port (5190).
Adds three test cases pinning the code-vocabulary section that frame-packets.mjs appends to code frames. Deleting codeVocabularySection outright left all 455 skills tests green before this change; the only assertion touching it was a doesNotMatch that passes trivially when the section is empty.
* docs(prompting): correct workflow one-liners against skill contracts
general-video leads with its positive identity and companion mode;
faceless-explainer keys on invented visuals instead of TTS;
talking-head-recut uses the 'graphic overlays' trigger term;
motion-graphics gains its input side and overlay output;
music-to-video stops implying images are required.
* docs(prompting): make vocabulary video grids readable
Replace the 4-5 column table hack with a 3-column CSS grid,
switch demo clips to autoplay muted loops (no black poster frame,
no player chrome over tiny videos), and align cells at 16:9.
* docs(prompting): document the opening interview and run-shape questions
The guide taught prompt shapes but never prepared readers for the
conversation that follows: the intent interview, the two run-shape
questions (storyboard, automation vs companion), the just-build-it
skip, and BRIEF.md as the resumable artifact. Add that section to the
overview, a disambiguation note on the storyboards page, and free up
'companion' as a reserved term in media-and-audio.
* docs(guides): make BRIEF.md the pipeline's Step 3 artifact
Step 3 (Strategy & Messaging) listed no output while describing
exactly what BRIEF.md now captures. Name the artifact in the step
table, project tree, step body, gate, and iterating list, and fix
SCRIPT.md's step label in the tree (Step 4, not 3).
* docs(quickstart): realign the setup surface with the skills catalog
The quickstart drifted from docs/guides/skills.mdx, CLAUDE.md, and the
prompting overview — it had never been updated when those surfaces were:
- `--full-depth` on both install commands, with the reason inline. Without
it `skills add` fetches the skills.sh registry blob, which lags `main` by
hours, so a reader following the quickstart installs stale skills.
- `check` in the `/hyperframes-cli` row, and a validate step in the manual
dev loop, which went preview → render with no gate at all. The prompting
overview calls `check` "the step people skip and regret" and states both
`lint` and `check` must pass before rendering.
- `/hyperframes-keyframes` in the core-skills table (8 rows → 9).
- `/figma` in the optional-workflow list (10 → 11).
* docs(skills): close the catalog drift class and complete the music-to-video input
Follow-up on the two review nits from #2872.
`/music-to-video`'s SKILL.md names three inputs — an audio file, a video to
pull audio from, or a track generated from a mood brief. Every compressed copy
of that description carried only the first two, and the third is the one that
makes "a complete video needs zero assets" true. Fixed on all eight surfaces
that state it, so no surface is now more correct than its siblings: the
prompting overview and quickstart setup tables, docs/guides/skills.mdx, the
README catalog, root CLAUDE.md + AGENTS.md, both CLI project templates, and the
router's own routes/music-to-video.md Input line (whose Interview must-haves
already listed all three).
The drift was structural, not accidental: the sync set declared in
docs/guides/skills.mdx and in CLAUDE.md's "Skill catalog maintenance" named
four surfaces and never the two setup tables, so those two were free to rot
while the declared four stayed correct. Both declarations now name them, and
both say the set applies to a *changed contract* — a reworded description —
not only to an added or renamed skill.
skills-manifest.json regenerated for the touched route file.
* docs(claude): point the routing-surface rule at routes/, not the moved stubs
Item 3 of "Skill catalog maintenance" still sent readers to
`references/workflow-catalog.md` for a workflow's input/output/trigger
contract and `references/route-briefs.md` for its interview entry. Both are
now "moved" stubs — the contract and the interview entry live together in
`references/routes/<workflow>.md`, one read per candidate route.
Same failure class the previous commit fixed at item 1: a maintenance rule
outliving the layout it describes. Swept the tree for other pointers at the
two stubs; there are none, so this closes it rather than fixing one instance.
The credited repo (github.com/nicoch/mediabunny) doesn't exist. The
correct upstream is github.com/Vanilagy/mediabunny, which matches the
package's npm registry metadata (repository field) and the MPL-2.0

* fix(lint): don't flag unresolved templating-token asset srcs as missing
The asset-src rules (audio_src_not_found, missing_local_asset, CSS url(),
and data-composition-src) treat any src that isn't a remote URL or an
__UPPER__ placeholder as a resolvable local path and error when the file
is absent. But the linter runs before any build/templating step, so a src
that still carries a late-bound templating token (<<token>>, {{ token }},
${token}) cannot be resolved statically and is not a missing file.
Add a shared hasUnresolvedTemplatingToken() predicate (alongside the
existing __UPPER__ tolerance) and skip such srcs at each asset-src site,
so unresolved templating tokens no longer surface as false-positive
"file not found / the rendered video will be silent" errors.

* fix(lint): check raw src for templating tokens before cleanAssetUrl; cover video/img/css + hevc
Addresses review. At the <video>/<img>/<source> and CSS url() sites the token skip
ran AFTER cleanAssetUrl(), which splits on ?/# and truncates inside a ${...} expression
(e.g. `${asset?.url}` -> `${asset`), so those sites still emitted the missing-asset
false positive for valid unresolved templates. Move hasUnresolvedTemplatingToken() onto
the RAW value at both sites, and extend the same skip to hevcPreviewLint (same
pre-substitution, cleanAssetUrl-first shape). Add regression tests for video/img/css
(including ?/# inside ${...}) and clarify the predicate docstring.

* fix(capture,audio): three defects found running product-launch-video end to end
Found while running the full product-launch-video workflow twice against a real
site (linear.app) to verify PRs #2880/#2881/#2882. All three are independent of
those PRs.
**Scraped SVGs were unusable as files.** `assetDownloader` wrote an inline
`<svg>`'s `outerHTML` straight to `assets/svgs/*.svg`. An inline SVG inherits its
namespace from the HTML parser, so `outerHTML` omits `xmlns` — valid pasted back
into HTML, but not a standalone document, and `<img src="logo-abc.svg">` renders a
broken-image icon. That is exactly how these assets get consumed. `toStandaloneSvg`
now declares the namespace on the way to disk (plus `xmlns:xlink`, but only when an
`xlink:` attribute is actually used). The filename hash moved to the bytes that
land on disk so it still cannot drift from content.
**`sfx: none` became a cue named "none".** `fetch-sfx` split the storyboard's
`sfx:` list and dropped only empty strings, so the absence marker reached the
engine as a real cue that could not resolve. The absence spellings are part of the
storyboard vocabulary; drop them.
**`bgm_pending` was lost translating neutral meta to product-launch meta.** A
detached Lyria/MusicGen generate leaves `bgm: null, bgm_pending: true` until the
track lands. `toProductLaunchMeta` returned only `{bgm, voices, sfx}`, so "not
ready yet" became indistinguishable from "silent by design" — and because
`fetch-sfx` rewrites `audio_meta.json` from the sidecar, a still-generating bed was
snapshotted away with nothing to signal it. The flag now survives, and `fetch-sfx`
warns when it snapshots a pending bed instead of leaving a silent film that the
storyboard claims has music.
Not included, deliberately: `assemble-index.mjs` rewrites `index.html` wholesale
and so discards the block `transitions.mjs inject` wrote, meaning any Step 6 rework
silently loses transitions. Fixing that means deciding whether assemble preserves an
injected block or inject becomes re-appliable — it touches both scripts and the
Step 5/6 ordering in SKILL.md, so it deserves its own change.

* feat(capture): re-add the full-page plate a scroll shot needs, at 1x
`product-launch-video` tells a scroll shot to animate a viewport over a full-page
capture. No such file existed: capture emits 15 viewport-sized scroll-position
tiles, and a plate is not substitutable by tiles — a viewport travelling down one
continuous image is the whole point.
An earlier `full-page.png` was dropped in 62b55171e because 1/8 agents read it and
the contact sheet covered the same ground. That measured it as a *comprehension*
artifact, on an eval where nothing was building scroll shots. The scroll shot is a
different consumer, so this brings the plate back — but not as it was, because two
things have to hold for it to be worth having:
- **Taken last.** After the scroll traversal, so lazy images have loaded and
scroll-triggered reveals have fired. A plate shot on arrival is full of blank
bands, which is a good reason for an agent to look once and never again.
- **Sticky chrome neutralised.** `fullPage` bakes a fixed header in at one
position, freezing a nav across the middle of the plate. The viewport tiles keep
sticky on purpose (natural browsing state); the plate cannot. Positions are
recorded and restored in a `finally`, so the extraction passes that run afterwards
see an unmodified DOM.
**1x, deliberately.** 2x is what you'd want to push in without softening text, but
doubling a long marketing page passes Chrome's 16384px screenshot cap precisely on
the pages that most want a scroll shot (linear.app: 10962 CSS px → 21924 at 2x). At
1x a 1920-wide plate is pixel-exact for a 1920x1080 viewport. A frame that needs
headroom captures its own region at 2x instead. Pages over the cap get no plate
rather than a silently clipped one, and the caller falls back to the tiles.

* docs(product-launch-video): point the scroll shot at the plate, make handoff fields binding
Two follow-ups from the same end-to-end runs, now that #2880 and #2881 have landed and
their sentences exist to edit.
**The scroll shot pointed at an artifact that did not exist.** #2881 said "use a 2x
full-page capture and animate the viewport over it". Neither half held: capture emitted
no full-page image, and 2x on a long marketing page passes Chrome's 16384px screenshot
cap precisely on the pages that most want a scroll shot. Both runs watched the agent go
looking, not find it, and improvise — once by re-capturing 2x strips per section, once by
using the native 1920x1080 tiles full-bleed. This PR's capture commit adds the 1x plate,
so the sentence can now name something real: the plate, its absence on pages too tall to
capture in one piece, the tile fallback, and why pushing in past 1:1 still wants a region
capture of its own.
**A constant field was being read as an absent one.** #2880 asks for x/y, scale, opacity
and direction/speed on every handoff. Across two runs on the same model, `opacity` went
0/12 then 12/12 — when the value never changes, leaving it out is a reasonable reading of
the instruction. But downstream an omission and "there is no handoff here" are the same
thing, so the field set has to be stated as binding even when constant. Same clause added
to the worker's side of the contract.
Validation: `bun run lint:skills`
* fix(capture,audio): close the three contract gaps raised in review
Review on #2892 (Rames, Magi) found the fixes correct inside the changed files but
incomplete at the contract level. All three hold up against source; two of the three
were reachable in production, and the plate one was self-inflicted by this PR.
**The plate guard checked a stale height.** `scrollHeight` was measured before the scroll
traversal and handed to the guard, but the plate is deliberately shot *after* it so lazy
content has loaded — and lazy loading grows the document. The guard's input therefore read
low on exactly the long pages it exists for, letting the check pass and a clipped plate
through, undetectable downstream because the skill only teaches the tile fallback when the
file is *absent*. `captureFullPagePlate` now measures the height itself at call time, and
verifies what Chrome actually produced by reading the PNG's IHDR before writing, since the
capture can trigger another round of loading. Over the cap, nothing is emitted.
**Assembly dropped the flag again.** `bgm_pending` survived into `audio_meta.json` but
`assemble-index.mjs` rebuilt its audio object from three named keys, so at the step that
actually builds the film "not ready yet" still looked like "silent by design" — this PR's
own framing of the defect, one layer further down. The flag rides along now, and a pending
bed with no file raises an anomaly instead of quietly assembling a silent cut against a
storyboard that promises music.
**The sibling adapters had both audio bugs, and there were two of them.** The review named
`faceless-explainer`; `pr-to-video` carries the same file. Its own test asserts the two are
byte-identical ("intentionally identical across the reusing skills"), so fixing one alone
broke that test — which is what caught the second copy. Both now carry the absence-sentinel
filter and the surviving `bgm_pending`, and `faceless-explainer` gets the same five
regression tests.
Also from review (Miga): the sticky-restore in `finally` is wrapped, so a page that broke
mid-capture cannot replace the real error with a cleanup one.

* fix(capture,audio): meet the two review asks I under-delivered on
Follow-up to 194fb6995. Re-read Magi's review body rather than working from the summary,
and two of the three blockers were addressed in spirit but not to the letter.
**The plate probed before neutralisation, not after.** 194fb6995 moved the measurement off
the caller's stale value and into the function, but took it before forcing fixed/sticky
elements to `static`. The review called this out specifically and is right: dropping those
elements back into flow grows the document, so the probe could still read under the cap on a
page that is over it once neutralised. The probe now runs after neutralisation and before the
shot, inside the same `try` so restoration still happens on the early return. Added the exact
case asked for — initial height under the cap, final height over it — asserting no
screenshot is taken, no file is written, and the page is still handed back unmodified.
**Assembly warned where the review asked it to refuse.** An anomaly in a list is not
enforcement: assemble is re-run on Step 6 rework, long after the audio step's warning
scrolled past, and a warning still lets a silent film out the door over a snapshot whose own
JSON says the bed is generating. `assemble-index.mjs` now dies on `bgm_pending && !bgm`, with
`--allow-pending-bgm` as the deliberate escape for previewing mid-generate. Pinned with three
tests in a new `assemble-index.test.mjs`: refusal writes no index.html, the escape assembles
and says so, and a film that is silent *by design* still assembles untouched — the
distinction the flag exists to make.

* fix(audio): carry the bgm_pending gate into the sibling assemblers
The remaining blocker, and one this PR created: the previous commit made all three copies of
the audio adapter *emit* bgm_pending, but only product-launch-video's assembler *reads* it.
So faceless-explainer and pr-to-video would do exactly what this PR set out to stop — parse
an audio_meta.json that says the bed is still generating and assemble the silent film without
a word. Producer fixed in three places, consumer in one, is worse than neither: before this
PR there was no flag to drop.
Both siblings now get the same three changes product-launch-video got — the flag carried
through the audio object, `die` on `bgm_pending && !bgm`, and `--allow-pending-bgm` as the
deliberate escape — plus the same three tests: refusal writes no index.html, the escape
assembles and says so, and a film that is silent *by design* still assembles untouched. That
last one is the one worth having; it proves the flag restored a distinction rather than just
adding a gate.
Applied as three separate patches rather than a file copy: these assemblers have diverged
(pr-to-video validates a bare `<template>` fragment where product-launch takes a `<div>`
root, which its fixture reflects).
`music-to-video` has the fourth copy of this assembler and is deliberately untouched: it has
no audio producer, and its assembler reads `{ voices: [] }` with no bgm path at all, so the
flag can never reach it.

The old demo argued that a locked frame crops the story. The sharper claim is
what a cut throws away: a move carries the spatial relationship between two
shots, a cross-fade carries none.
Five stages each get their own colour and the halves diverge on how the next
colour arrives -- in place, or by travelling to it. 30-47% of pixels differ,
against 3% for every version where the WITHOUT half moved the content.
That 3% is the trap now documented in the rule: translating the scene and
translating the camera are the same transform, so sliding content past a fixed
frame is not a static comparison, it is the same shot rendered twice.
Embed is cache-busted to -v2; docs images carry immutable year-long cache, so
reusing the filename would serve returning visitors the old render.

CodeQL (incomplete multi-character sanitization, code-scanning/803) on
the script-stripping regex added in c61a24b51 — a failing check, and
correct: a single replace can reform the pattern it just removed, since
`<scr<script>ipt>` leaves a whole `<script>` behind.
The security framing does not apply — the stripped string is counted and
discarded, never rendered, inserted, or served — but the incompleteness
is real for this use: a reformed tag survives into the match pass and
perturbs the element count the routing gate reads. Suppressing a gate
over a technicality when the fix is four lines is the wrong trade.
Now loops to a fixed point. Terminates by construction: each iteration
either strictly shortens the string or changes nothing and exits.
Regression covers the reform case and an unterminated `<script>` that
must not spin; fault injection confirms the reform test fails under the
old single pass.

Review findings on #2891. Two of them bite directly on this PR's own
purpose — making the fleet element-count distribution readable — so they
are fixed rather than noted.
countElementTags counted `</` + letter anywhere, including inside inline
JS. A compiled comp containing `const h = "</div>"` or a template literal
building `</span>` inflated the count once per occurrence. Compiled comps
embed large inline scripts, so the bias is systematic, not noise, and it
lands entirely on the ~83% of renders with no probe session — precisely
the cohort this PR exists to characterize. Script and style bodies are
now stripped before matching; losing their own closing tags costs 1-2
counts against a threshold in the thousands.
The new elementCount fell back to 0 when its page.evaluate threw,
following the tweenCount pattern beside it. For this field that pattern
is wrong: evaluate failures concentrate on the huge-DOM compositions the
field is meant to observe, and a 0 there is indistinguishable from a
legitimately empty comp, so the fleet p50/p99 would absorb both silently.
It is now undefined on failure, the INIT console line omits the token
entirely rather than emitting a zero, and the parser reports absent —
mirroring the live/static provenance split the routing resolver already
uses.
Also documented: the "every render reaches this path" claim holds only
for renders that survive to end of init, so the tail is survivor-biased
and should be read as a lower bound; and the two element-count fields now
say plainly which is which — composition_element_count gates routing,
observability_init_element_count is the observational counterpart — so
the follow-up analysis can't query the wrong one.
Nits: envInt is integer-only per its name, both live-DOM reads use
getElementsByTagName (live collection length, no NodeList materialized on
the 40k-node tail), and the attribution block notes that it runs with
routing off by design.
Fault injection confirms the new tests bite: disabling script stripping
fails 4, and the zero-vs-undefined case is pinned separately.

The short-comp routing gate can only read a live element count when a
probe session exists, and the first v0.7.83 data shows that is far rarer
than estimated: 17% of renders (86/503), not the ">=28%" the video-presence
proxy suggested. The other 83% fall back to a static source scan, which
is exactly blind to the shape that motivated the live count — small
markup, thousands of script-created nodes.
That leaves the fleet element-count distribution unknowable for most
renders, and the observed distribution is already surprising: p99 ~900,
max 1,420 against a 2,500 ceiling calibrated on 7k/20k/40k synthetic
nodes. Either the ceiling is close to irrelevant, or the large-DOM tail
is hiding in the 83% we cannot see. Both readings change what PR B
should do, and neither is decidable from probed renders alone (they are
a biased sample — they got a probe *because* they carry media or
unresolved compositions).
So measure it where every render already goes: capture-session init.
`collectSessionInitTelemetry` gains a querySelectorAll("*") count beside
the tween count it already collects, riding the same channel to
`observability_init_element_count`. This is observational only — capture
has begun, far too late to route on — and it deliberately does not feed
the gate. It answers the distribution question the gate cannot.
Coverage for this channel is proven rather than assumed: the tween-count
fix that shipped in v0.7.83 took the clamped-parallel bucket from 0/272
renders to 217/217, and 23.1% -> 100% overall.

Live telemetry panel, an isometric deploy pipeline wider than the frame, and
a progressive edge rollout across twelve regions. In each, the rule follows
from the content rather than being applied to it.
Rule 2's demo carries the strongest evidence in the chapter: deleting the
three stages the locked frame never shows and re-rendering leaves that half
identical on all 180 frames.
Rule 3 gains a rule-level distinction the rebuild surfaced — stagger what is
happening, not what is merely present.

Replaces the generic card/chip/disc subjects with ones where the rule is
unavoidable given the content: a payment sheet over a receipt, a split-flap
departure board, and a render-farm corridor.
Rules 5 and 6 in the grammar list were one-liners that under-said what their
demos prove. Rule 5 now carries the mass claim, the follow-through lag, and
the transforms-only caveat (a counter that overshoots renders a false value).
Rule 6 credits occlusion over blur and prefers one foreground element.
Section intro no longer endorses over-cranking; every movement in an applied
half has to finish "this moves because...".

The guides were previewing five-second catalog snippets - a chart block standing in
for an explainer, a caption component standing in for a recut. Each now opens with a
cut from an actual film made through that workflow: the Huly launch for product
videos, a SpaceX valuation piece for explainers, one shoot cut three ways for
captions and recuts, a real pull request for PR videos, a per-listener year in
review for motion graphics, a beat-analysed track for music, and a timeline-editing
film for the custom path. Captions name what each clip is from instead of implying
it is a finished film for that page.
music-to-video had no media at all and now does, because the honest asset existed
all along: a 90-second film built from an analysed track.
slideshow still has none. Nothing on disk honestly shows a navigable deck, and a
stand-in on a page about that specific output would be a small lie.
Re-rendering these projects was tried first and rejected. Fresh renders regressed:
variables-launch lost its centre creator clip and rendered white where footage
should be, and the pull-request and cloud films came out two to three seconds short.
The projects reference media that has moved since they were made, so the existing
exports are the better source until each project's paths are repaired.
EaseCurveSection.tsx was 635 lines against CI's 600-line cap, which has
been failing the File size check on main for four consecutive runs and
blocks release cuts.
Moves the two self-contained presentational pieces into a sibling
EaseModeControls.tsx, following the pattern the directory already uses
(easeCurveSvg, easePresetLibrary, EaseParamFields): the mode radio group
(EaseModeToggle) and the preset grid (EasePresetGrid), plus the mode
vocabulary they own — EASE_MODES, the EaseMode type, MODE_LABELS,
DEFAULT_EASE_BY_MODE, and the DEFAULT_CURVE/Pts pair those defaults are
built from. Both components are stateless: they take the current
selection and emit a committed ease string, so nothing had to be
rewired. Only the symbols the parent still references are exported —
EASE_MODES and DEFAULT_EASE_BY_MODE became file-internal, since the
components that consume them moved too.
No behaviour change. EaseCurveSection is now 556 lines, the new file 110.

The hero was an 11MB export of the website-launch film. The finished master is
36.3s at 8.15 Mbps, so the page now serves a high-quality encode made from that
instead - 9MB at CRF 21, which is oversampled for a column under 900px wide.
The colour-grading film was also being derived from a 1080p variant while a
3840x2160 60fps master sat on disk. Its tile and full film are now encoded from
that master.
Both are published under versioned filenames. The first upload set
max-age=31536000, immutable, so the CDN edge kept serving the old bytes when I
replaced the objects in place - the corrected files measured identical to the
originals over HTTP until they were renamed. The component takes optional tile and
full overrides per film so a single asset can be revised this way without renaming
the rest.
Worth recording plainly: none of these films were rendered for the docs. They are
existing renders, transcoded down for the web, so each one's quality is capped by
whatever file already existed. Re-rendering from the launch projects at 4K60 would
raise that ceiling.
