/* ==========================================================================
   KWEEK — AUTH DESIGN SYSTEM  (v2)
   Concept: the auth card reads as a payment receipt — Kweek's own product
   signature (verified receipts) — torn/perforated edge, dashed rules, a
   rotated "verified" stamp, monospace transaction-style footer meta.
   Canvas is a quiet dark ink field so the paper card pops. Space Grotesk
   everywhere; Space Mono for receipt-style data.
