/**
 * Rushcart marketing site — one stylesheet, every page.
 *
 * ## The system, in one paragraph
 *
 * Big type, big radii, flat tinted cards, and no line art. A section is an eyebrow, a very large
 * headline, one line of support, then a row of cards. A card is a small grey label, a bold sentence,
 * and an illustration filling whatever space is left. The fills alternate down a page — paper, quiet,
 * cream, brand, night — and that alternation is the rhythm, doing the work borders and icons used to
 * do here.
 *
 * ## Why the icons are gone
 *
 * The previous version hung a 22px stroked pictogram over every heading. At that size a wallet, a
 * receipt and a card are the same grey scribble, so they carried no information and cost the page its
 * calm. What replaced them is either a real illustration (drawn to this palette, in `assets/art/`) or
 * nothing at all. The only SVG left in the markup is the menu button, which is UI, not decoration.
 *
 * ## Palette
 *
 * The UI colours ARE the illustration colours — `hero-courier.svg` and everything under `assets/art/`
 * is drawn from the twelve values below. That is what keeps a red card and the artwork sitting on it
 * looking like one object rather than a stock image dropped into a brand.
