/*
 * pinthoppers.com - the one stylesheet (T45, D-A30; two themes since T48, D-A35;
 * the landing page since D-A70).
 *
 * THE COLOURS ARE THE APP'S, BY NAME. Each `--color-*` below is a role from
 * `src/ui/tokens.ts`, and `tests/web/site.test.ts` compares the values and the
 * text/background pairs used here with that file's `readablePairs`, so the site
 * cannot drift to a contrast nobody measured. No hex appears outside the two
 * palette blocks. (Lower case because Prettier writes CSS hex that way; the
 * test compares without case.)
 *
 * TWO PALETTES, ONE SET OF RULES. The light palette is the top-level `:root`,
 * the dark one the `:root` in the `prefers-color-scheme: dark` query under it,
 * and the page follows the reader's system theme as the app does. Every rule
 * below is written once, by role, and the dark block does nothing but redefine
 * the palette: that is what lets one pairs check hold in both themes, so the
 * test refuses a dark block that restyles anything. It also refuses one that
 * forgets a role - the role would keep its light value, and the light text on
 * the dark ground is 1.28:1.
 *
 * `color-scheme` tells the browser the page comes in both, so what it draws
 * itself (the policy table's scrollbar, any form control) follows the theme
 * too. It is here and not in a `<meta>` in each page: the stylesheet is
 * render-blocking, so the browser knows it before the first paint, and the
 * declaration sits beside the palettes it describes.
 *
 * ONE FONT FILE, SERVED FROM HERE. Headings are Righteous, the app's heading
 * face (`src/ui/fonts.ts`), so the site reads as the app does. It is the same
 * OFL file the app bundles, served from this origin with its licence beside
 * it (`/fonts/OFL.txt`) - no font service, no request anywhere else; the CSP
 * allows `font-src 'self'` and nothing more. Body text stays on the system
 * face: the policy pages are read, not admired.
 *
 * THE LOOK IS A PASSPORT (D-A70, the owner's choice on 2026-09-27): heavy
 * outlines, hard offset shadows, colour blocks with hard edges, and the app's
 * round Mile stamp (`src/ui/RouteStamp.tsx`) drawn large. The blocks use the
 * pairs the app measured and no others: the warm ground carries `text` and
 * `textMuted`; the amber block carries `onAccent` ONLY. A dark green block with
 * cream text in the light theme would be a pair nobody measured, so there is
 * none.
 *
 * THE AMBER BLOCK SETS THE COLOUR OF EVERYTHING IN IT. A rule written for the
 * whole page (`a`, say) would put `text` on amber, and in the dark theme `text`
 * is the cream: 1.91:1. The pairs check reads a selector's own background or
 * its ancestors', so every rule inside `.rule` names `onAccent` itself, and the
 * block holds no link.
 *
 * THE APP'S OWN DRAWINGS, NOT NEW ONES. The icon, the map pin
 * (`assets/map`), the Mile stamp and the hop mark (`assets/brand/hop.png`) are
 * what the app draws; the site reuses them. The hop appears once, beside the
 * sentence about the name, as it does in the app's About screen (D-A28): it is
 * a signature, not a motif, and is tinted with `visited` as the app tints it.
