/* The phone text sheet (js/phone-sheet/phone_sheet.js) and the brain dump's
 * keyboard bar (js/brain-dump-sidebar/brain_dump_phone_bar.js).
 *
 * Neither is behind a media query: both are only ever MOUNTED on a phone, by JS
 * that asks `isPhone()`, so a rule here cannot leak onto a desktop layout.
 *
 * 🔴 `bottom` is the keyboard, not zero — `--dn-keyboard-inset` is published by
 * js/mobile/mobile.js (≈0 on Android, where the viewport already shrank; the
 * keyboard's height on iOS). Same contract as the long-term popup's phone sheet.
