/* ═══════════════════════════════════════════════════════════════════
   SFSC Cart Drawer (v2) — site-wide right-side slide-in.

   Rebuilt from scratch to match the "Retail Cart and Checkout" Claude
   Design comp 1:1. Icons are Material Symbols Outlined (the comp's own
   icon set), type is Inter + JetBrains Mono. Tokens lifted verbatim from
   the comp frames (#303030 ink / #005BD3 accent / #E3E3E3 hairlines).

   Served from a NEW path (cart-drawer.v2.css) to defeat the Pressable
   edge cache that was pinning the old asset by path.

   Markup contract (cart-drawer.php) and data contract (sfsc_get_cart /
   sfsc_update_cart_item / sfsc_remove_cart_item) are unchanged.

   State machine:
     [data-state="open"|"closed"]                     → drawer open/close
     [data-cart-state="loading|empty|error|populated"] → which body shows
