/* Design tokens for the QR order-and-pay demo (Stop 19, a made-up Sydney Road café).
   Brand colours (--brand, --brand-ink, --signal) are overridden per café from cafe.json at runtime.
   Fonts:
   - Archivo (wide, 112-125 width, heavy): the display face. Its expanded cut reads like tram-stop and street signage,
     which is where the table-number plate idea comes from. Used for the café name, numbers and headings only.
   - Figtree: the body face. Open, friendly and very clear at 14-16px on a phone read at arm's length at a sunny table,
     with plain, even numerals for prices (we tried Atkinson Hyperlegible Next first; its slashed zero made $5.20
     look like a code). */
