/* ───────────────────────────────────────────────────────────────────────────── Self-hosted UI typefaces. Everything here is served from our own origin — no fonts.googleapis.com, no third-party connection on the critical path, and no reliance on whatever the OS happens to ship. The whole point is that Studio renders identically on macOS and Windows; system font stacks (SF Pro vs Segoe UI, SF Mono vs Consolas) are exactly what we're getting away from. Three families, three jobs — see --font-display / --font-ui / --font-mono in style.scss: Outfit Variable display — panel titles, buttons, brand moments Inter Variable UI — 11-12px labels, values, lists, tables (body) JetBrains Mono mono — IDs, hashes, coordinates, embed code Both sans faces are VARIABLE (wght 100-900), so any weight is free — reach for 450 or 650 when the design wants it instead of rounding to 400/500/600/700. Files are vendored into static/fonts/ui/ from these npm packages (kept as devDependencies so the version is tracked and re-copying on upgrade is easy): @fontsource-variable/outfit 5.3.0 @fontsource-variable/inter 5.3.0 (wght-only axis — the opsz/standard builds are ~71KB vs 47KB and we don't drive optical size) @fontsource-variable/jetbrains-mono 5.3.0 unicode-range keeps the non-latin subsets off the critical path entirely: they are fetched only if such glyphs actually get rendered (e.g. a Cyrillic entity name out of a GLB). Latin-only session = 31.5 + 47.1 + 39.5 ≈ 118 KB. NOTE: Outfit has no Cyrillic — upstream ships latin + latin-ext only. Cyrillic inside a --font-display element falls through to Inter via the stack below. GOTCHA — these filenames are NOT content-hashed, and vercel.json serves /static/fonts/* with `max-age=31536000, immutable`. Upgrading a font package and overwriting the same filename would leave existing users on the old face for up to a year. When you bump a package, RENAME the file (e.g. append the version) and update the src below. Same lesson as the R2 cache-header note in CLAUDE.md: with immutable caching, new bytes need a new path. ───────────────────────────────────────────────────────────────────────────── */ /* ─── Outfit Variable — display ─────────────────────────────────────────────── */ @font-face { font-family: 'Outfit Variable'; font-style: normal; font-display: swap; font-weight: 100 900; src: url('static/fonts/ui/outfit-latin-wght-normal.woff2') format('woff2-variations'); unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+0304, U+0308, U+0329, U+2000-206F, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD; } @font-face { font-family: 'Outfit Variable'; font-style: normal; font-display: swap; font-weight: 100 900; src: url('static/fonts/ui/outfit-latin-ext-wght-normal.woff2') format('woff2-variations'); unicode-range: U+0100-02BA, U+02BD-02C5, U+02C7-02CC, U+02CE-02D7, U+02DD-02FF, U+0304, U+0308, U+0329, U+1D00-1DBF, U+1E00-1E9F, U+1EF2-1EFF, U+2020, U+20A0-20AB, U+20AD-20C0, U+2113, U+2C60-2C7F, U+A720-A7FF; } /* ─── Inter Variable — UI / body ────────────────────────────────────────────── */ @font-face { font-family: 'Inter Variable'; font-style: normal; font-display: swap; font-weight: 100 900; src: url('static/fonts/ui/inter-latin-wght-normal.woff2') format('woff2-variations'); unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+0304, U+0308, U+0329, U+2000-206F, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD; } @font-face { font-family: 'Inter Variable'; font-style: normal; font-display: swap; font-weight: 100 900; src: url('static/fonts/ui/inter-latin-ext-wght-normal.woff2') format('woff2-variations'); unicode-range: U+0100-02BA, U+02BD-02C5, U+02C7-02CC, U+02CE-02D7, U+02DD-02FF, U+0304, U+0308, U+0329, U+1D00-1DBF, U+1E00-1E9F, U+1EF2-1EFF, U+2020, U+20A0-20AB, U+20AD-20C0, U+2113, U+2C60-2C7F, U+A720-A7FF; } @font-face { font-family: 'Inter Variable'; font-style: normal; font-display: swap; font-weight: 100 900; src: url('static/fonts/ui/inter-cyrillic-wght-normal.woff2') format('woff2-variations'); unicode-range: U+0301, U+0400-045F, U+0490-0491, U+04B0-04B1, U+2116; } @font-face { font-family: 'Inter Variable'; font-style: normal; font-display: swap; font-weight: 100 900; src: url('static/fonts/ui/inter-cyrillic-ext-wght-normal.woff2') format('woff2-variations'); unicode-range: U+0460-052F, U+1C80-1C8A, U+20B4, U+2DE0-2DFF, U+A640-A69F, U+FE2E-FE2F; } /* ─── JetBrains Mono — monospace ────────────────────────────────────────────── */ /* Variable (wght 100-800), not the static weights.
