   Metric-compatible fallback — fixes the mobile English layout shift.

   Measured defect: at 390x844 the hero CTA row needs 349.2px inside a 354.5px
   container, so it has 5.3px of slack against 237.2px of button text — it
   tolerates only +2.2% of text widening. With font-display: swap the system
   fallback paints first, and Helvetica/Arial run +4.8% wider than IBM Plex Sans
   Arabic. The row therefore wrapped to two lines, and when the webfont arrived
   it unwrapped: the row collapsed 116.8px -> 52.4px, the hero lost 64.4px, and
   everything below it moved. Measured 0.2363-0.2385 on every cold load, all of
   it in a single shift entry.

   390px is the only affected width. 360 and 375 already wrap with the webfont,
   so they are stable in both states; 414 has 11.8% of tolerance; every Arabic
   width has 8.7% or more.

   Vertical: read from the font itself (unitsPerEm 1000, hhea ascent 1085,
   descent -415, lineGap 0), then divided by size-adjust so the overrides
   resolve against the adjusted em. That compensation is not optional — measured
   without it the fallback's line box lands 1-2px SHORT of the webfont's, which
   trades a horizontal shift for a vertical one. Compensated, both render an
   identical 24px line box.

   Horizontal: size-adjust is set so the fallback is never WIDER than the
   webfont, because only a wider fallback can wrap a row the webfont fits.
   Measured against Helvetica Neue this face renders 6.9% narrower at 95%, which
   still fits on a platform whose matched face is up to ~9% wider than Helvetica
   — DejaVu Sans being the widest realistic match. A fallback that cannot be
   wider makes the reflow impossible rather than merely unlikely.

   local() only: no extra request and no bytes on the wire; verified by request
   log. Ordered most- to least-preferred, the trailing group covering minimal
   Linux images and headless CI containers where none of the first seven exist
   and this face would otherwise be inert.

   Residual condition, documented rather than hidden: on a platform with none of
   these 13 faces the stack falls through to ui-sans-serif, which measures +2.7%
   — just over the 2.2% tolerance — and the shift would return.
