/* ── FONT STRATEGY ──────────────────────────────────────────────────────────
   We use only system fonts so the site looks IDENTICAL whether opened via
   file://, http:// or inside Claude. No external requests needed.
   - Display (headings): "Barlow" is pre-installed on most Android devices.
     Fallback chain hits something bold & condensed on every platform.
   - Body: Roboto is the Android system font. Clean identical everywhere.
