/* css/style.css — Table Order customer app
   ================================================================
   Design notes:
   - Warm neutral background, not the cream+terracotta combo — this
     restaurant's own primary/accent colors (set in admin settings)
     carry the brand identity, so the base palette stays quiet.
   - System font stack only, deliberately. Restaurant WiFi/mobile data
     is often slow — a webfont means a flash of unstyled text on every
     first load, which matters more here than on a dashboard.
   - Signature: the Table N pill stays visible in the header across
     every screen. It's the one piece of context ("who am I, where
     am I") that must never get lost in a shared-device ordering flow.
