/* Metrics-matched fallback faces: while the woff2 files are still loading
   (font-display: swap), the local fallback renders with the web font's
   proportions instead of its own, so the font swap does not reflow the page.
   size-adjust was calibrated on the site's own text (scripts/audit/font_probe.py
   harvests real text runs and ratios webfont/fallback widths) because the
   OS/2 xAvgCharWidth heuristic mispredicts the pair by ~25 points. Two
   2026-08-30 recalibration attempts were rejected with numbers: per-weight
   faces (+56px doc delta vs +32px baseline) and a re-measured scalar
   (117.26% moved an EN paragraph past a wrap boundary, +56px); the original
   117.08% stays because the harness says it is the best measured value on
   this machine.
   Weight verdict, same session: the serif family renders ONLY at weight 400
   (+ italic 400) on this site — headings are mono — so per-weight serif
   faces have nothing to match. Rerun the probe if serif headings are ever
   added.
