/* =============================================================================================
   The static blog and landing pages (web/site). Loaded AFTER the app's entry stylesheet, which carries the
   tokens (`src/ui/tokens.css`), the Space Grotesk faces, the legacy `.header`/`.nav-link`/`.btn` rules and
   the blog's `.footer*`/`.skip-link` (components/layout/layout.css) — so a blog page wears the app's chrome
   with zero JavaScript, and this file restyles that chrome to the 2026-10 Shell (REBUILD_PAGES §A: a 56 px bar
   on `--color-bg` with a hairline, the wordmark at 600, nav links with the accent rule under the current one,
   one primary door; a footer on `--color-bg-elev` with the EU line, the links and the seller as fine print)
   and styles what is new: a reading column, cards, the table of contents.

   Rules this file keeps (pinned by site/site.test.ts and scripts/check-ui.mjs):
   - tokens only: no colour literal anywhere, no px radius, no px font size, no numeric z-index;
   - breakpoints 480 / 720 / 1000 / 1280 only (`src/ui/breakpoints.ts`);
   - no animation, and every transition on a `--dur` token so reduced motion zeroes it;
   - no JavaScript is ever needed: everything here works on a page that ships none.
