/**
 * Gist /join Page Styles — Paid Onboarding
 *
 * SYNCED WITH: extension/ui/brand.css and src/styles/try.css.
 * /join is the canonical purchase entry point for both web-first and
 * store-first acquisitions. The page is intentionally narrow and quiet:
 * one column, generous whitespace, type doing all the work, a single
 * primary action below the fold.
 *
 * DESIGN INTENT (Jony Ive notes):
 * - The interface disappears so the offer leads.
 * - Every state is designed: signed-out, unpaid, paid, beta-ended, error.
 * - Motion only appears at the seams between states. No decorative animation.
 * - The price selector is a single segmented control, not two competing cards.
 *
 * TOKENS — match try.css and brand.css. Keep these in sync if brand.css moves.
