/* ── Font-metric fallbacks — kill the swap reflow ──────────────────────────
   While Chakra Petch / Sora stream in, text renders in local Arial adjusted
   to the webfont's measured widths, so nothing rewraps when the swap lands
   (the hero-sub gaining a line was a 0.13 CLS on desktop). size-adjust
   values are MEASURED against the Google-served faces (canvas measureText,
   100px, long mixed sample) — remeasure if the font subsets ever change;
   ascent/descent are divided by size-adjust per css-fonts-5. Line-heights on
   this site are all fixed numbers, so widths are the only metrics that can
   move layout. Browsers without size-adjust ignore these faces (no change).
