/* CountMesh web app.
 *
 * The palette is the product app's, taken from `app/lib/theme/bar_theme.dart` rather than
 * re-chosen, so the web and the phone are one product. Every text/surface pair there is checked
 * against WCAG AA in the app's `theme_contrast_test.dart`; re-picking colours here would quietly
 * leave that behind.
 *
 * Dark-first on purpose: this is read in dimly lit storerooms and bars. `--primary` is reserved
 * for actions and focus. The status hues never touch an interactive element — a red button must
 * not be able to mean "out of stock".
