/* ============================================================================
   ROGUE AI — WEBFONT DELIVERY
   TDR-111 conformant: self-hosted OFL variable fonts, woff2 only, explicit
   font-display, metric-adjusted fallbacks. No third-party CDN in the export.

   The export does not depend on fonts.googleapis.com. If the woff2 files under
   assets/fonts/ are absent, the metric-adjusted fallback faces below take over
   and the layout does not reflow — it degrades to the system stack at the same
   measure. See FONTS-README.md for the exact Fontsource files to drop in and
   the recorded licences.

   Load order:  fonts.css  ->  tokens.css  ->  components.css

/* ------------------------------------------------- metric-adjusted fallbacks -
   Provenance: the four override values below are the published Fontsource /
   next-font metric-override figures for these two families, NOT figures
   measured in this project. They are here so a missing woff2 does not reflow
   the page. Verify with a reflow test before rollout: render a 60-character
   line at --text-doc-body with the woff2 blocked, and confirm the line box
   height and the line-break position are unchanged.

   This is the one axis in this system carrying values we did not compute
   ourselves. It is recorded in review/DEVIATIONS.md as D-06 rather than
   presented as measured.                                                     */
