Alexander	c73363e93d	fix(shopping/loyalty): emit FNC1 codewords for Supercard ... Coop Supercard uses GS1 Data Matrix — the payload contains FNC1 separators between fields, not literal 0x1D bytes. Enable bwip-js parsefnc so ^FNC1 placeholders in the env value produce genuine FNC1 codewords (codeword 232), matching the physical card and letting checkout scanners parse the GS1 element string.	2026-04-23 21:04:56 +02:00
Alexander	0ab98690eb	feat(shopping): loyalty-card modal with build-time barcodes ... Adds a CreditCard button on the shopping list that opens a modal showing the user's Coop Supercard (Data Matrix) and Migros Cumulus (Code 128). Card numbers come from SHOPPING_COOP_SUPERCARD_NUMBER and SHOPPING_MIGROS_CUMULUS_NUMBER env vars; a prebuild script renders each to an SVG (~1-2 kB) in static/shopping/ so no barcode library ships to the client. Cards missing their env var are silently skipped, and the generated SVGs are gitignored to keep personal numbers out of the repo.	2026-04-23 16:21:15 +02:00
