/* Modal — the reusable dialog shell (components/modal.js).
 *
 * The backdrop is a blurred, dimmed page: a light tint plus
 * `backdrop-filter: blur(var(--backdrop-blur))`. When backdrop-filter is
 * unsupported the @supports block below falls back to a heavier solid dim so
 * the page behind still reads as out of focus. The panel scrolls internally;
 * on phones it becomes a near-full-screen bottom sheet, safe-area aware.
 *
 * Colour, type, spacing, radius and motion come only from tokens.css:
 * --backdrop-dim, --backdrop-solid, --backdrop-blur, --modal-surface,
 * --modal-border, --modal-radius, --modal-shadow, --modal-pad, --modal-max-w.
 * No literal colours anywhere here.
