Introduces a shared email module that wraps all transactional emails in a
cohesive dark-themed template matching the site's visual identity (Barlow
font, #14171e background, #adf661 CTA buttons, logomark PNG header).
- app/lib/email.server.ts: new module with sendEmail, wrapInEmailTemplate,
emailButton, emailParagraph, and escapeHtml helpers; Resend instance is
lazily initialized as a singleton
- public/email-logo.png: 96×124px PNG of the logomark for email use (SVG
gradients are not supported in Outlook)
- auth.server.ts: password reset and email verification now use the branded
template; errors are thrown so Better Auth can surface failures
- support.tsx: internal notification uses sendEmail; adds a user-facing
branded confirmation email (fire-and-forget so failures don't surface to
the user); plain text fallback included
- scripts/sync-prod-db.sh: remove first_name/last_name from sanitize query
(columns were dropped in #399)
- 13 unit tests covering all template helpers
