/**
 * Membership + Checkout page chrome.
 *
 * Depends on membership.css, which owns the .upd-btn family and .upd-plans.
 * Adopts the same local token set .upd-auth-card declares, so /membership/ and
 * /checkout/ sit in the one dark panel language the member surfaces share
 * rather than a parallel palette that almost matches.
 *
 * Mobile-first: base rules are the small-screen case, min-width only.
