/* Phone composition: iPhone SE (375 CSS px wide) is the 1x reference.
   Width controls bounded spacing/art growth; height never enlarges type.
   Typography grows more gently than illustrations. No root scaling, CSS zoom
   or whole-page transform. UI-08 reuses this composition on portrait tablets
   with one bounded unit; landscape and desktop remain independent.

   Keep this after the section and desktop-scale styles. Match api.compactQuery
   in js/main.js. These are layout boundaries, not device detection. */
