/* Billing pages (Phase 3). Tokens only — no hardcoded hex anywhere in
 * this file. Layout: plan cards grid on desktop, stacked on phones.
 * Tables scroll horizontally with sticky first/action columns on narrow
 * widths (pre-deploy skill: card transforms only for simple lists). */
/* v0.6.0: explicit breakpoints so the 4th card never orphans onto its
 * own row (auto-fill did exactly that at shell widths). Cards are equal
 * height: the feature list stretches and the button sits at the bottom. */
