Landing performance: flag font subset, responsive mascots, AVIF cache, HTML minify
- 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.
