/* Watchtower in Decipher's look. The tokens are Decipher's frontend/app/globals.css, the shapes
   its components/ui: the app top bar (title, centred search pill, user menu), the sidebar on the
   page ground, the page as one raised surface (PageSurface), summary widgets (WidgetRow + Metric),
   SectionCard, Table, Badge, Button, ToggleGroup, InteractiveEmptyState.
   Light or dark follows the system; the theme item pins one (data-mode, set before paint).
   Every colour token is light-dark(light, dark), so one block serves both themes. */
