Product updates.

Added public pricing, in-app billing, Polar checkout plumbing, webhook idempotency, and paid plan limits.

InstaRenewal now includes paid plan definitions, a public pricing page, an in-app billing settings page, Polar checkout and portal routes, signed webhook handling, usage visibility, and over-limit warnings. The Free plan remains available after email verification. Paid plans are ready for real checkout once Polar product IDs and webhook secrets are configured in production.

Added account settings, workspace settings, password reset, email verification foundations, and quality gates.

The production expansion foundation added account settings, workspace settings, reset-password flows, verification token infrastructure, quality gates, and public copy cleanup.

Added email verification, verified-user product access, and Free plan activation with usage limits.

New accounts now verify their email before full product access. Verified users receive the Free plan automatically and plan limits are enforced for clients, assets, SSL checks, reminder emails, and reports.
