/* The CLVR website (ADR-059).
 *
 * Colours come from the app: the graphite, white and bulb light of the screens before sign-in
 * (`DSBrand` in DesignSystemKit) and the app's green for actions (`DSColor.accent`). Green is for
 * buttons and small highlights only; amber is only ever the bulb's light. Backgrounds stay neutral.
 *
 * The page starts in the device's light or dark setting. Pressing the bulb overrides it for the visit
 * (`data-theme` on <html>, set by theme.js). The two dark blocks below must stay identical.
 *
 * No inline styles anywhere on the site: the pages are served with `style-src 'self'`.
