   Meal Mate — design tokens
   Concept: a market ledger. Dark "stall counter" sidebar + warm paper
   content area, receipt/ticket motifs throughout (dashed rules, perforation
   dots, a literal thermal-receipt shopping list). Mono numerals everywhere
   money or macros appear, to read like a till rather than a brochure.
