Beat-driven speed ramp, freeze-frame hit, and hard cut for music-led
promos and montages. Contributed as #2957; applied here as content so the
whole catalog set lands together.
Verified by rendering: 6s, clean, deterministic (the one Math.random hit
is a comment above a fixed pattern array). Opaque root, so no demo.html
is needed for its catalog preview.

Adds three themed registry families contributed by @jbernard077:
- mk-* minimal presentation (7 blocks, 3 components)
- yt-* retro-broadcast creator (5 blocks, 4 components)
- hw-* hand-drawn scribble (6 blocks, 5 components)
Consolidates PRs #1933, #1992, #1993 and #1994, cuts 5 of the original 34
items, and fixes the defects that CI never got to report.
Cut (5), each covered by something we already ship or trivial to inline:
- yt-doc-lower-third — would be the 12th name/role lower third next to the
10 lt-* variants and lower-third-bild
- mk-logo-sting — logo-outro exists, and yt-logo-intro is the richer version
- mk-cta-button, mk-pill-callout, yt-avatar-pip — a styled button, a styled
chip and a masked circle
Fixes:
- hw-path-text rendered as a solid black blob. #hw-pt-path is the textPath
carrier and had no rule, so it inherited SVG's default black fill while
only #hw-pt-guide set fill:none.
- mk-line-graph value labels collided with their own dots and each other.
Series after the first now label downward, and the offset moved off a CSS
transform because the entrance tween animates y and GSAP rewrote it.
- Added demo.html for the 11 components and the 3 transparent-root blocks.
Without it generate-catalog-previews.ts skips components entirely, so the
catalog-previews job failed for every component in the original PRs.
- Tagged hw-title, hw-pipeline and hw-path-text as overlays.
Also registers all catalog pages in docs.json, which the original PRs left
orphaned, and picks up 4 pre-existing blocks that had no catalog page
(camcorder-hud, editorial-flash-overlay, freeze-frame-dressing,
organic-light-leak-overlay) because the regenerated nav now links them.
Every item was verified by rendering it and looking at the frames.

* docs(registry,skills): surface code-highlight 0-based indexing and opacity-reveal sweep guidance
From the 2026-07-14 CLI feedback digest (skills-owner action): a user
building code teaching videos hit two authoring gaps.
1. code-highlight's `line` is intentionally zero-based (`line: 1` =
second displayed line) but the warning lived only in pr-to-video's
code-vocabulary reference — nowhere an author actually touches the
value. Call it out at the block-use sites: the `__BLOCK` declaration
itself, the registry-item description, and the motion-graphics
catalog map.
2. Opacity-only code-typing tripped `sweep_static` for that user, who
worked around it with a slow host y-drift. The sweep fingerprint
does include per-element opacity, so document the actual trap (a
reveal that settles before the sampled window, then holds a static
frame) and the idiomatic fixes (spread the reveal / keep a blinking
caret alive) in the check reference — and pin the fingerprint's
opacity sensitivity with a regression test covering both the
visibility-floor crossing and a mid-fade value change.
* docs(catalog): regenerate code-highlight page from updated registry-item description
Only the code-highlight page is committed: a full generate-catalog-pages
run also surfaces ~34 blocks missing from the git-tracked catalog index
(pre-existing drift on main), which belongs in its own chore PR.
Adds a Code Animations catalog section — 9 self-contained, installable blocks:
morph, snippet-flight, typing, diff, highlight, scroll (DOM/GSAP) and 3d-extrude,
shader-dissolve, particle-assemble (WebGL). Each block ships only its own effect and
renders deterministically (paused GSAP timeline seeked per frame, seeded RNG, no
render-time data fetch). Wires the catalog nav, registry.json, a new code-animation
Studio category, and preview assets.
