   multipliers (1.05 / 1.6) so vertical metrics don't matter; only advance
   width does. size-adjust values are measured, not guessed: at the hero's
   own sizes Bungee sets ~0.92x the width of Arial Black, and Be Vietnam Pro
   ~1.10x the width of Segoe UI. Re-measure with canvas measureText if the
   faces are ever swapped.
   Honest scope: this narrows the fallback-to-real jump, but did NOT measurably
   move aggregate CLS (0.013 desktop before and after). The residual is a
   spread of sub-0.02 swap shifts across the chips, nav and hero — well inside
   the 0.1 "good" threshold, and not worth reshaping the hero to chase. */
