 * Digital Trust Monitor web app -- shared styles.

 * Palette and type extracted from scripts/status_page.py's Navy design
 * (see that file's own comments for why Navy: the register of banks,
 * insurers and law firms the actual buyer persona -- a non-technical
 * owner at a small real-estate/insurance/legal/accounting practice --
 * already reads as trustworthy). Kept as CSS custom properties so the
 * status pages and the app chrome stay visually one product, not two.

 * Checkbox/radio OPTION labels (a label directly wrapping its own

 * checkboxes and its plan radio buttons) are the actual tap target --
 * the browser toggles the input when ANY part of the whole label is
 * tapped, not just the native control's own tiny box. Left as a plain
 * inline label, though, that clickable box was only as tall as a single
 * line of text (well under 24px), far short of the 44px minimum every
 * other control on this page already meets (see .btn's own min-height
 * above). Real, measured gap found building J18 (mobile tap-target
 * checks, docs/launch/PLAN.md §8's own E2E table) --
 * tests/e2e/journeys/mobile-signup.spec.js asserts these labels'
 * bounding boxes are >=44x44px. inline-block (not flex) so the long
 * consent sentence keeps wrapping normally at the viewport's own width
 * instead of being laid out as rigid, non-reflowing flex items.

 * latter -- confirmed live: the browser's own console reported real
 * style-src violations (report-only, non-blocking) for every inline
 * style="" this app shipped with, the first time these pages were
 * actually opened in a browser under the app's CSP. Fixing this at the
