/* Casa - house grocery inventory. Personal app, not BTZ-branded.
   Look (2026-11-02 redesign): "labelled storage zones". A light sage page,
   white cards, one colour + icon per place in the house (pantry terracotta,
   fridge teal, freezer ice blue, garage slate, supplements plum), and a
   three-bar stock meter for Have / Low / Out. Bricolage Grotesque for titles
   and numbers, Figtree for text. Sentence-case labels, rounded rectangles
   (never pills), tap targets 44 px and up. Phones: bottom bar. Computers
   (960 px and up): side rail, centred content, centred sheets. */
