/* ── Metric-matched fallbacks (prevent CLS on font swap) ──
   Before the real font arrives, the browser uses the fallback. Normally this
   causes layout shift when the swap happens because metrics differ. By giving
   the fallback ascent/descent/size overrides that match the real font, any
   swap causes ZERO reflow. Values calibrated against the real DM Sans and
   JetBrains Mono metrics (from the fontsource/screenspan calculator).
