/* ============================================================================
 * TESI Trainer — Notification system styles (scoped: every class is ttn-*)
 * Uses the app's existing design tokens (--bg*, --accent*, --t1/--t2, --bdr,
 * --el-*) so it is automatically light/dark-aware via html[data-theme]. Kept in
 * its own file so it can never disturb existing component CSS.
