/*
 * read-aloud.css — Oplæsnings-tilstand (window.ReadAloud)
 *
 * Styles the portal-wide read-aloud framework defined in public/js/read-aloud.js:
 *   - the speaker toggle (top-bar slot + modal-header mirror)
 *   - the playback control bar (fixed top-bar overlay OR modal-header host)
 *   - the karaoke word highlight (.ra-word / .ra-word--active)
 *   - the "no audio" red blink on the visible toggle
 *   - long-press selection/callout suppression while mode is on
 *
 * All colours via design tokens (var(--hd-*)); no hex literals (hex-zero gate).
 *
 * Cascade layers (docs/architecture/design-system.md §Fase 1 Foundation):
 *   reset -> tokens -> base -> components -> utilities -> overrides
 * These rules live in @layer components.
 *
 * Layout note: the overlay bar mirrors player-top-bar.css exactly (visual-
 * viewport offset vars + --player-top-bar-height) and sits above the portal's
 * fixed slide-out chrome (z-index 10120 > the karakterark panel's 10113), so it
 * occludes the menu/panel while playing. Inside a top-layer <dialog> the top-bar
 * (and this overlay) is painted over, so the controls are instead hosted in the
 * modal header, on their own wrapped row — see .hd-ra-controls there.
 *
 * Compat: Safari 16.6 / iPadOS 16. Active-word highlight uses box-shadow (not
 * padding) so karaoke never reflows the text. Touch targets >=44px (WCAG 2.5.5)
 * via a transparent ::after hit-area so the visible icon stays discreet.
