/* Broadstairs Records Hub — Sambrook's brand design system.
   Matches the sambrooksbrewery.co.uk look: white banners, bold black uppercase menu/buttons (Jost),
   Assistant for text/headings, blue kept only as a logo accent.
   Mobile-first, high contrast, large touch targets for wet/bright/gloved brewery-floor use.
   Traffic-light + pass/fail colours are deliberately universal (never restyled into brand colours). */
