/* notifications.css — dropdown de notificações (issue #343).
 *
 * IMPORTANTE: o projeto usa tokens Material Design 3 (--surface,
 * --on-surface, --outline-variant, etc., definidos em tokens.css).
 * NÃO usar --card/--text/--line/--muted — esses não existem e o
 * `var()` cai pro initial value (transparent / preto) — popover ficou
 * transparente em prod no primeiro deploy do #343 antes deste fix.
 *
 * Fallbacks (#hex) garantem que mesmo sem tokens.css carregado o
 * popover renderiza visível.
