Replaces the bundled percentage-keyframe model with per-property-group
tweens. Each studio operation creates/edits only its own group's tween:
drag → position, resize → scale/size, rotate → rotation.
Includes off-screen element indicators with drag-to-move, unclipped
overlay for off-screen interaction, gesture recording replacement,
and all 6 root cause foundation fixes from the keyframe trace
investigation.
Plan documents are working artifacts that shouldn't be committed.
Removes three plans that were accidentally tracked and adds
docs/plans/ to .gitignore to prevent future occurrences.
Compositions are now self-contained: the compiler captures font files
and embeds them as woff2 data URIs, eliminating silent render-time
fallback when the render environment lacks the author's fonts.
Resolution order (each tier falls through to the next):
1. Existing @font-face → use as-is
2. Bundled alias (38 cross-platform mappings) → embed data URI
3. Google Fonts → fetch, cache, embed
4. Local system font → locate on OS, compress to woff2, embed
5. Local @font-face paths → read file, compress, inline as data URI
6. External CDN stylesheets → fetch CSS, extract @font-face, inline
7. Alias map fallback → closest bundled equivalent
8. Actionable error with guidance
Key changes:
- System font locator (macOS/Windows/Linux) with path-bounding and
symlink defense (realpathSync + O_NOFOLLOW)
- woff2 compression via wawoff2 (WASM, cross-platform)
- Multi-weight/style variant capture with length-sorted token matching
- External stylesheet inlining with SSRF defense (assertPublicHttpsUrl,
HTTPS-only, private-host blocking, 2MB cap, 4-concurrent limit)
- Studio auto-import via GET /fonts/file API + renderAliasFor() derived
from shared FONT_ALIAS_MAP (no more hand-curated drift)
- failClosedFontFetch throws on unresolved fonts in distributed renders
- Single source of truth: @hyperframes/core/fonts/aliases
- system_font_will_alias lint rule (escalates to warning for distributed)
- Default to Inter + JetBrains Mono in templates and CSS reset
React components and DOM utilities for the snap system:
- SnapGuideOverlay: pre-allocated div pool (6 guides + 4 spacing)
for ref-driven guide line rendering during drag
- SnapToolbar: magnet/grid toggle with S/G keyboard shortcuts,
right-click grid popover for spacing config
- GridOverlay: CSS repeating-linear-gradient grid, GPU composited
- snapTargetCollection: walks iframe DOM tree to collect visible
elements as snap targets, cross-iframe safe (nodeType check)
