/**
 * fonts.css — self-hosted webfonts (design.md §4.1: "Self-host woff2 with separate
 * Arabic and Latin unicode-range subsets; font-display: swap; preload the Arabic
 * display woff2 on AR pages").
 *
 * Files live in `public/fonts/` (docs/04-architecture.md §6.1: "public/ # static:
 * fonts/ (self-hosted woff2 subsets)") and are vendored from Google Fonts — the
 * canonical open-source (SIL OFL) distribution of every face design.md names (Oswald,
 * Inter, Changa, Readex Pro, IBM Plex Mono). Each `unicode-range` below is the same
 * per-script split Google's own font API computes; only the `latin` cut is kept for the
 * Latin-only faces (Oswald/Inter/IBM Plex Mono never render Arabic text — design.md
 * §4.1's font-stack-* split guarantees that), and BOTH `latin` and `arabic` are kept
 * for Changa/Readex Pro, because `:lang(ar)` scopes the whole document subtree and a
 * short Latin run can still appear inside it unwrapped (e.g. this file's own S1–S10
 * range in the shell-smoke copy) — see design-tokens/arabic-rtl skills.
 *
 * `font-weight` is written as a RANGE ("200 700") for the four faces design.md marks
 * "(variable)" §4.1 — these are the true variable-axis files, not static instances, so
 * `font-weight: 500` etc. resolves through real interpolation exactly as the direction
 * spec requires ("the ink can be matched by eye rather than by number. Keep it.").
 * IBM Plex Mono is NOT variable per §4.1, so its two weights are two static files.

/**
 * RESOLVED 2026-08-19 (was "KNOWN GAP" below, read before adding a font here): the
 * wordmark placeholder used U+27E8/U+27E9 MATHEMATICAL LEFT/RIGHT ANGLE BRACKET, which
 * no shipped face (Oswald, Changa, Inter, Readex Pro, IBM Plex Mono) contains — nor does
 * any redistributable open font, per the `fontTools` inspection of Google's own
 * "Noto Sans Symbols 2" this note originally recorded — so the browser fell through to
 * a system font for just those two characters (Cambria Math on Windows/Chromium),
 * reported by `scripts/visual_qa.mjs` as `font-fallback`/`ar-font-fallback`. Remedy (b)
 * from the original note was taken: design.md §2.4's `wordmark-text-en`/`-ar` now read
 * U+2039/U+203A (‹ ›), the SAME bracket already used for every other pending-marker in
 * design.md (§11.9's own `‹pending›`), which IS covered by the latin subset above with
 * zero rendering compromise — confirmed by a zero-high `visual_qa.mjs` re-run
 * (`docs/ui-evidence/a2-identity/visual-qa`). `src/views/macros/chrome.html` and
 * `office-chrome.html` carry the literal; do not reintroduce U+27E8/U+27E9 there.
