   overdb — product page
   Loaded BEFORE ../theme.css, like the sibling pages. theme.css owns every
   shared surface; this file owns only the overdb app mocks. Everything here
   is namespaced `odb-` so it can never collide with the mock classes the
   theme already knows about (.app-body, .card, …).

   Palette follows the app's own dark theme (src/renderer/styles.css
   `.dark` in the overdb repo): violet accent, amber warn, emerald good.
