All checks were successful
Deploy to Production / Deploy to Server (push) Successful in 1m8s

- Add /change-email as a proper standalone page (public/src/change-email.html)
  with API key input, new email input, verification code flow, and success state
- Update footer partial: change "/#change-email" link to "/change-email" on all pages
- Remove email change modal HTML and hash-handler JS from index page source
- Add /change-email to sitemap.xml
- Rebuild all HTML files via build-html.cjs

- Add updateEmailByCustomer() to src/services/keys.ts
- Add customer.updated webhook handler in src/routes/billing.ts
  to sync email changes made via Stripe dashboard back to DocFast
