/* =============================================================================
 * Stryde SDK — Notification Center (BRD: Notification Center v1.0).
 *
 * The bell + drawer chrome, served at /sdk/notifications.css and injected by
 * /sdk/notifications.js. SELF-CONTAINED on purpose: the platform's surfaces use
 * different ad-hoc token names (the launcher's --line2/--soft, the apps' HSL
 * channels, the wiki's --glass) — so this widget carries the Stryde palette
 * itself (the exact warm-beige / deep-purple values + violet→azure gradient,
 * 18px radius, glass blur, --ease) and themes off `.dark` / [data-theme=dark].
 * That makes the notification center pixel-identical on EVERY surface (launcher,
 * wiki, app detail, shell host, and inside hosted apps) regardless of host CSS.
 *
 * RTL-safe (logical properties throughout). All `.sn-*` classes are namespaced.
 * ========================================================================== */
