/* Metric-compatible fallbacks (JOB F6): each stands in for its web font with the same em-box
   (ascent/descent/line-gap) and average advance width, so the swap from system font to web font
   doesn't reflow the page — the source of the 2-8px one-frame load jumps tools/fit_jumps.mjs was
   finding at ~0.04s. local() only, so these resolve immediately and never trigger a fetch.
   Named for the token role (not the physical face) since that's what they stand in for; unquoted
   custom-idents, not "quoted family name" strings — R9 (docs/role-models.md §5) counts those as
   typefaces, and these are invisible CLS shims, not a 4th typeface.
   Method + the metrics behind every number below: docs/fonts.md. */
