/* ══ Mobile / touch ═══════════════════════════════════════════════════════════
   The editor was built mouse + keyboard first. These rules add a touch-usable
   layout and on-screen controls, gated on `.is-touch` (set from
   matchMedia('(pointer: coarse)')) plus a phone-width query — desktop is
   untouched. Corner dragging is replaced by a joystick, so the canvas can own
   pan/pinch gestures without any drag-vs-scroll ambiguity. */
