- Flag font: ship a committed fontTools subset (43 KB, -45%) of
TwemojiCountryFlags.woff2 with only the 15 flags the site uses, under a
content-hashed name with a preload on every flag-bearing page. The build
validates the subset against a manifest and fails when a new flag
appears without regenerating (npm run subset-flags). JS subsetters
(subset-font/harfbuzzjs) were rejected: their wasm builds silently drop
the COLR/CPAL color tables, rendering all flags invisible.
- Responsive mascots: legal/join/404 pages served 434-500px sources for
175-180px slots; the build now emits 180w/360w variants (AVIF 1x: ~7 KB
vs ~22 KB) and the pages use srcset. Small logo spots (14-42px) now use
the existing 64/128px variants instead of the 256px file.
- injectAvifPictures copies the img sizes attribute onto the AVIF
<source>; without it Chrome mis-selects w-descriptor candidates and can
drop the image entirely.
- AVIF conversion is cached by content hash (.avif-cache.json); the old
mtime check never hit because copyDirSync refreshes mtimes, so every
verify re-encoded all 26 files.
- HTML output is minified (comments + indentation, <pre> preserved,
newlines kept for inline-script safety): index.html 121 KB -> 93 KB.
- unicode-range trimmed to U+1F1E6-1F1FF; tag-sequence flags fall through
to the system emoji font.

- New hero headline "Turn any video into a watch party" with animated
gradient highlight, sharper subtitle and quiet trust line under the CTAs
- Changelog badge redesigned as the koala's speech bubble (version and
release date baked in at build time, no version.json fetch anymore)
- Light/dark theme toggle in the header (dark default, pre-paint via
lang-init, full light theme across sections)
- Use cases and "Why KoalaSync" merged into one section with the three
strongest feature tiles; question-mark koala moved to the FAQ
- FAQ and self-hosting setup collapsed by default via shared
section-collapse component (hash deep links auto-open them)
- Compat/juggler section more compact
- og:image switched to the 1280x640 repository OpenGraph card (landing
and join page), generated during build
- "watch party" keyword added to meta title/description in all 15 locales
- All em-dashes removed from user-facing copy
