/**
 * Cart page — band, line-item list, estimated total, empty state.
 *
 * Patterned on Shopify's default cart page, wearing the Ocean Calm tokens.
 * The band mirrors the page-head section so the cart reads as the same site;
 * its rules are repeated here (and in account.css) because the section's
 * stylesheet only ships on section-built pages. Tokens only; hairlines use
 * the `thin` keyword, fixed dimensions use rem.
