/* Remote modal v2 (GoodQA #55, Tisha Becker's 2026-09-29 spec) + the device row.
 *
 * Self-contained: every rule is scoped under `.rm-*`, nothing here restyles the
 * legacy device menu (#deviceMenuOverlay) or any shared class. Loaded on every
 * page load but INERT while the flag is off (js/remote-modal.js
 * REMOTE_MODAL_V2 = false): no element carries these classes until the flag is on.
 *
 * DEVIATIONS FROM THE SPEC, each on purpose (recorded again in
 * plans/LANE-remote-modal-u1-u2-20260929.md):
 *   D1  Close button 44x44 (spec: 36). The spec's own section 8 demands 44px targets.
 *   D2  Green TEXT is #1F7A46 (5.34:1 on white), not #3FA66C (3.05:1). #3FA66C is
 *       kept only where it is decoration (nothing uses it now).
 *   D3  Gray TEXT is #5B6472 (5.98:1), not #8A93A3 (3.1:1). The "›" chevron is
 *       decorative but uses #5B6472 too so one grey exists.
 *   D4  Website-tile icon stroke is #1F7A46 on #E3F5EA (spec #3FA66C, 2.69:1 < 3:1).
 *   D5  Chips, rotation pills, More options, Open buttons are 44px tall (the
 *       prototype's padding gives ~33-40px).
 *   D6  Text never below 13.5px.
 *   D7  Field/chip/option/pill EDGES are #6B7485 (4.7:1 on white), not the prototype's
 *       ~16% ink (about 1.4:1): a control's boundary needs 3:1 (WCAG 1.4.11).
 *       Tile edges stay the spec's light 1px: the tile's icon+label identify it.
 *   D8  Lock/Add-time icon strokes are #5A48C0 / #A8630A (spec #6D5BD0 / #C2760A) so
 *       each clears 3:1 on its own tint. The tints and every other icon colour are the spec's.
 * Every text/background pair below is MEASURED in a real browser by
 * platform/test/remote-modal-a11y-ui.test.js ("CONTRAST measured").
