Billing Page

Self-serve tier upgrade / downgrade page.

The legacy /dashboard/billing link from the dashboard upgrade banner used to 404 (the page was referenced but not implemented). Customers who'd hit their credit cap saw the 'Upgrade tier' button, clicked it, and landed on a dead page, then went hunting through the Stripe portal where the only visible action was 'Cancel'. One confirmed support ticket (Bryce, 2026-05-11) from this exact path.

This page shows the customer's current tier, recent usage, and one-click upgrade buttons that POST directly to /billing/checkout for each higher tier. Downgrade routes through the Stripe Customer Portal which they can also reach from here.
