/* billing-flow.css
 *
 * Visual reskin classes ported from design/billing-flow.html. Only the
 * classes actually referenced by the four billing templates are kept here
 * (sect-card, sect-head, sect-title, sect-sub, brand-mark, banner, plan-pill,
 * renewal-note, selected-plan-banner, invoice-table, inv-status, seg-tabs,
 * seg-tab, pane, back-link, pill-default, plus a .pay-stripe .lock-meta
 * extension for the existing cs-components.css rule).
 *
 * Loaded only on:
 *   - templates/account_billing.html
 *   - templates/account_payment_methods.html
 *   - templates/payment.html
 *   - templates/pricing.html
 *   - templates/subscribe.html
 *
 * cs-components.css already owns .pay-grid, .pay-card, .cc-preview,
 * .summary-row, .plan-grid, .plan-card, .plan-features, .billing-toggle,
 * .save-tag, .btn-grad-wide, .acct-row, .acct-row-l, .acct-row-name,
 * .acct-row-sub, .acct-row-actions, .page-title, .page-sub,
 * .page-eyebrow, .page-header, .pay-stripe, .cs-empty-state,
 * .cs-modal-*, .cs-toast-fixed — we don't re-define those.
