/**
 * SS Membership — Checkout / Signup chrome
 *
 * Consumes the --ssc-* token contract from SS Commerce UX Standard v1.1.
 * Owned per-module (no SSH_Checkout component). Token names are the contract;
 * this file is one of several module implementations of those tokens.
 *
 * Token defaults are declared on .ssm-checkout itself as fallbacks so the
 * module renders correctly even when no theme-level :root tokens exist.
 *
 * Visual register:
 * - 720px max column, centered
 * - No border-radius
 * - 0.5px borders
 * - Sentence-case headings; CTAs uppercase
 * - Charcoal hero default; theme may override via :root --ssc-* declarations
