 * EZ Connect — Floating Actions

 * Both mobile and desktop use the same FAB (bottom-right) + panel pattern:
 *
 *   Mobile  (< 768 px): panel slides up as a full-width bottom sheet.
 *   Desktop (≥ 768 px): panel appears as a compact 248 px card above the FAB.
 *
 * Panel structure (shared across breakpoints):
 *   ┌─────────────────────────┐
