Matches the latest reference more closely: a Featured/Tokens/Boosts/
Content/Customization/Bundles tab row (only Featured is populated -
the rest are inert labels since there's no real data behind them
yet), per-card checkmark feature bullets, and a Popular badge on the
Exam Simulation Token card. Client-side presentation only, no backend
changes.
Replaces the plain title/list layout with a header, a coin-balance
summary card, and a product card grid (icon, description, price,
solid Buy button) matching the app's existing card/badge visual
language. Only the two real products render - no fabricated
categories or bundles, since the backend doesn't have that data yet.
