/*
  IBM Plex Sans Arabic — self-hosted (US-LEG-008 #892, BR-910).

  The SPA must not load assets from a third-party origin: a font CDN discloses every
  visitor's IP and User-Agent to its operator, which is a cross-border transfer needing
  a docs/security/ropa.md §2 row. These faces are served from our own origin instead.

  Provenance: copied verbatim from @fontsource/ibm-plex-sans-arabic@5.3.0, which mirrors
  Google's own subset split — so the unicode-range values below are lifted, never retyped.
  All four subsets Google served for THIS family are vendored, so everything Plex used to
  render still renders identically; unicode-range still means a visitor downloads only the
  subsets they actually render. (Inter, which used to sit second in the stack, also carried
  greek / greek-ext / cyrillic-base / vietnamese, which Plex does not ship — see the note in
  src/index.css and docs/design-system.md § Typography.)
  Licence: SIL OFL 1.1 — see fonts/LICENSE.txt, which must ship alongside these files.

  woff2 only: every browser this app targets has supported it since 2016, so the legacy
  .woff fallback fontsource also ships would be dead weight in the image.

  ⚠ nginx serves /fonts/ with "Cache-Control: public, immutable" for a year
  (infra/docker/nginx.conf.template), so a client will NOT revalidate these bytes. Unlike
  /assets/ the filenames are not content-hashed, so the guard is the VERSION DIRECTORY:
  bumping the @fontsource package means writing /fonts/<new-version>/ and pointing these
  rules at it. Never overwrite a file in place — a re-subsetted face under an existing
  name would be served stale for up to a year, and a rollback could not reach it.

  This file itself is deliberately at the dist ROOT (/fonts.css), not under /fonts/, and nginx
  exact-matches it with `expires -1` (→ no-cache) while the binaries above stay immutable. That
  is load-bearing: with no caching header at all a browser applies heuristic freshness and serves
  it from disk cache with no request for weeks, so a visitor could keep pointing at a retired
  version directory long after a bump.

  ⚠ BUT `no-cache` DOES NOT SURVIVE THE EDGE, so this sheet does NOT "revalidate on every load"
  in any deployed environment (US-LEG-009 #928). Measured 2026-08-08, BOTH hostnames:

      origin direct (railway host)   Cache-Control: no-cache
      through Cloudflare             Cache-Control: max-age=14400   cf-cache-status: REVALIDATED

  So a real visitor can hold a STALE /fonts.css for up to ~4 HOURS.

  ⚠ AND THIS IS NOT SPECIAL TO THIS FILE. /favicon.svg measures identically (no-cache at the
  origin, max-age=14400 through the edge) — it is simply another `expires -1` response at a path
  whose extension Cloudflare considers cacheable. ANY file dropped into frontend/public/ with a
  static extension inherits this; a root sw.js would be the nasty version. What is NOT rewritten
  is what the edge does not cache (`cf-cache-status: DYNAMIC`): /, /index.html, /version.json.
  Do NOT reason from "the immutable ones passed through, so immutable protects you" — those
  responses also carry max-age=31536000, far ABOVE the 4h TTL, and Cloudflare does not shorten a
  longer origin TTL. The TTL comparison is the likely mechanism; `immutable` was never shown to
  be doing the work, and a hypothetical `max-age=600, immutable` is probably rewritten too.

  OPERATIONALLY, when you bump the font package: DELETE THE OLD /fonts/v<version>/ DIRECTORY IN A
  LATER RELEASE, NEVER IN THE ONE THAT BUMPS. Deleting it alongside the bump 404s every face for
  anyone still holding the old sheet, silently dropping them to system fonts — the exact failure
  the version-directory scheme exists to prevent. Resist the temptation to convert that into a
  stopwatch ("wait 4h"): the 4h is a CLOUDFLARE ZONE SETTING that lives in no file in this repo,
  "one release cycle" is NOT a safe proxy for it (staging rolled twice 53 minutes apart on
  2026-08-07), and neither bounds a long-lived tab — a register open across a shift keeps the old
  sheet's font-face rules in its CSSOM, and subsets are fetched LAZILY on first glyph need, so it
  can request a v<old> woff2 hours in. The whole directory is ~324 KB; keeping one stale copy for
  a release is cheaper than being wrong about any of that.

  ⚠ NEVER write one of this file's own rule tokens into this comment block. fontManifest.test.ts
  counts them across the WHOLE file without stripping comments, so prose that merely MENTIONS one
  is counted as a real rule and reds the build. This paragraph broke it exactly that way once, and
  the first attempt at warning about it broke it a second time by quoting the tokens as examples.
  Hence no examples here: grep the regexes in fontManifest.test.ts if you need the list.
