   Culture & Clay — Kombucha Brewing Tools & Journal
   Natural fermentation aesthetic: organic, soft, airy, generous whitespace.
   Palette: Sage Green #6B8F71 · Cream #F7F4EC · Terracotta Clay #C97B5A
            Charcoal #2F2E2A · Soft Amber #D9A441
   Deliberately unlike the industrial gray / deep blue / amber-gold brewery
   site: light cream grounds, serif display headings, pill buttons,
   16px card radius, whisper-soft shadows, no heavy borders anywhere.
