/* ===================== Ava — the hub's helper (ava.js) =====================
   A round button bottom-right, and a calm panel above it (440×640 on a computer, full height with Expand; a full-screen
   sheet on a phone). Built on the shell's colour variables, so light and dark both work. Motion is CSS only and stops
   for prefers-reduced-motion. */
