/* ══════════════════════════════════════════════════════════
   MemAero CART DRAWER + CHECKOUT MODAL
   Re-skinned from type19specialists/public/css/cart-checkout.css
   to the MemAero light theme using --color-* tokens from
   src/styles/memaero-tokens.css (loaded globally).

   Key changes from type19 source:
   - Dark-surface values (#1E2F36, rgba(0,0,0,0.25) backgrounds,
     rgba(255,255,255,*) borders) replaced with light-surface values
     (#FFFFFF, #EDEAE4, rgba(20,23,26,*) borders)
   - Form input colours flipped to dark text on white background
   - Stripe Elements appearance updated in memaero-cart-ui.js (theme:'stripe')
   - Pay-spinner card uses white card on near-black scrim
   - All t19-* selectors renamed memaero-*
