Upgrade wuff to 0.2.9 with compatible version requirements in the layout
and renderer test dependencies. Add a regression proving that corrupt
Brotli data returns a decode error and preserves an existing font.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- cargo nextest run --no-fail-fast: 17574 passed, 13 skipped
- Release verification: the previous SIGABRT sample renders with fallback;
valid-font screenshots remain byte-identical
Move Fontconfig matching, substitution policy, and the Fontique lookup cache into moli-system-fonts. Keep CSS family adaptation in moli-layout, migrate tests and fixtures, and retain the Skia notice in source comments.
Memoize a single-element property batch without building a full index, and derive one temporary sizing lookup per Document for multi-element observations. Route DOMSnapshot style collection through the shared observation and keep all projections scoped to the synchronous read.
Cover query counts, missing boxes, cold and mock reads, snapshot replacement, iframe isolation, and Inspector and DOMSnapshot capture paths.
Retain the sampled CSS sizing basis alongside frozen geometry. Resolve width and height only from an existing snapshot for the owning Document, without creating or refreshing layout; preserve style-only fallbacks otherwise.
Cover sizing boxes, zoom, replaced elements, Chromium-derived cases, and demand-driven snapshot lifecycles with renderer, layout, and CLI regressions.
Split screenshot and screencast capture contracts, publish one shared visual resource generation, and collect CSS image references during the real layout traversal. Add asynchronous publication and multi-session screencast regressions.
