/* Marketing site — static pages only.
 *
 * These pages are plain HTML. They never load React, the router, Firebase, or
 * the app stylesheet, so this file has to stand entirely on its own. Keep it
 * small: it is the whole cost of a marketing page load.
 *
 * Colours are duplicated here rather than imported from tokens.css on purpose.
 * tokens.css carries the full app palette; these pages need eight values, and
 * pulling the rest in to avoid repeating them would defeat the point.
