/* ng-voice-mobile.css — VOICE MODE, the phone-first full-screen voice surface
 * (2026-09-05). the operator's ask, verbatim: "speak, see it's being processed,
 * review the last few chats, switch chats, see pinned chats" — on an iPhone.
 *
 * Scope discipline: EVERYTHING here lives under #nvm-fab / #nvm-root, which
 * ng-voice-mobile.js creates. No existing selector is touched, so desktop
 * 1440px renders byte-identical with this sheet loaded. The FAB is the only
 * element visible before the overlay opens, and it only paints <=1024px
 * (phones + iPads); NGVoiceMobile.open() can still summon the overlay on any
 * width for testing.
 *
 * iOS notes baked in:
 *   - env(safe-area-inset-*) on header + bottom stack (viewport-fit=cover is
 *     already in the page meta).
 *   - touch-action:none + -webkit-touch-callout:none on the PTT button so a
 *     long-press is a recording, not a text-selection callout or scroll.
 *   - no <input> anywhere in the overlay -> no iOS focus-zoom to defend.
 *   - all animation gated behind prefers-reduced-motion: no-preference.
