/* ============================================================
   ATLAS — Notification Center FULL PAGE (V5)  ·  css/v5-notifications.css

   This is the full-page Notifications view (data-view="notifications"),
   distinct from the top-bar bell drawer (#notif-center, css/notifications.css).
   The bell drawer shows a few recent items as an overlay; THIS page is the
   complete activity log with filtering, archiving, and in-page preferences.

   THEME (atlas-dashboard.md #4): every color is a theme var
   (--panel/--panel2/--border/--border2/--text/--text-dim/--muted/--accent/
   --accent-rgb/--good/--warn/--bad/--champagne/--champagne-soft) so light +
   dark + per-tenant brand theming all read correctly with zero hardcoded hues.

   NO-SCROLL RULE (#3): the page lives inside the .canvas flow like every other
   atlas-view; the FEED scrolls internally (.ntf-feed), the outer 1080 frame
   never does.

   DATA INTEGRITY (data-integrity.md): the page renders only items handed to it
   by js/notifications.js. Counts come from real item state. The empty state is
   an honest "all caught up" — never a fabricated number.
