/* ---------- Web fonts (self-hosted woff2) ----------
   Stack rationale (legal-brief logic, not consumer SaaS):
   • JetBrains Mono — UI, citations, headings, code, all metadata. The voice.
   • Newsreader     — long-form serif body for editorial/docs + writ subtitles. The reading.
   • Inter          — interface body for forms/tables where mono is too dense.
   No Roboto. No Helvetica. No Fraunces.

   Fonts shipped from web/assets/fonts/ (woff2 only, latin subset). A regulator-
   grade compliance product should not load fonts from a third-party CDN —
   Google Fonts leaks the referrer and is blockable in EU privacy reviews and
   in China. Self-hosted: all font requests stay on warrant.build. */
