   Pantry — homeBuddy's fridge door
   Vanilla CSS, no build step, no remote assets. Ledger's sibling: same
   primitives (tokens, 44px taps, dock/toasts, skeletons), but light-first —
   this page gets opened in a bright kitchen, not in bed — and one accent
   axis instead of two: TIME. Everything color-coded here answers a single
   question, "how long has this got?": red past / amber soon / green fine.
   Nothing else is allowed to be red, amber or green.
