   Metric-tuned fallback faces — minimize layout shift during swap.
   Overrides computed with the fontaine/next-font formula from Capsize
   metrics: size-adjust = (web.xWidthAvg/web.uem) / (fallback.xWidthAvg/uem);
   ascent/descent/line-gap overrides normalized by (web.uem * size-adjust).
   Applied to serif (headings/editorial) and sans (body) — the type where
   reflow actually matters. Mono is small/inline; it keeps its system stack.
