/* ============================================================
   WHEELS ON FIRE — the design tokens.

   Every colour, measure and type stack the site uses, in one place.

   They were written out seven times: here, in page-head.css, in
   tour-colours.css and again inline in index, tours, bikes and contact.
   All seven copies held the same values, which is luck rather than
   design — nothing kept them in step. chrome.css, cta.css and site.css
   are all written against these names, so this file has to load before
   them; build-chrome.mjs and build-tours.mjs guarantee that.

/* A button with no author colour falls back to the browser's own, and on iOS
   that is the system blue — which is how the level cards in the booking form
   came out with a bright blue heading on a phone while they were black on
   every desktop we checked. Inheriting instead means a button always takes the
   colour of the text around it, here and in anything added later. */
