/* ===== Diekastautofill — cart, checkout, order, track (Phase 3) =====
   Additive only. /styles.css owns the shell, buttons and type; /css/store.css
   owns the catalogue UI. Everything here is commerce UI in the same language:
   bone + cobalt + lime, 2.5–3px ink borders, hard offset shadows, Space Mono
   for labels. Breakpoints match v2 exactly: 880px and 520px.

   MOBILE FIRST — most Indian traffic is mobile, and this is the one flow where
   a cramped layout costs an order. Single column by default; the two-column
   cart/checkout grid only appears from 880px up. Every tap target is ≥44px and
   every numeric input opens the numeric keypad (inputmode is set in the HTML).
