/* ============================================================
   Dispatch — monochrome Apple HIG, sized for mobile perfection.

   Palette: the neutral greys from gabrielepizzi.com / gbrlpzz/index
   (#f5f5f7 field, rgba(0,0,0,.85) ink, rgba(0,0,0,.55) dim) — no
   colour tint anywhere. Dark mode mirrors them on pure black.

   Typography: root font = -apple-system-body so iOS Dynamic Type
   scales the whole interface; every text size is rem, and the
   surfaces (cards, pills, rows) scale with it. Touch targets are
   ≥44pt (HIG minimum). Reduced motion is honoured.
