+# Email Templates Instructions
+
+This package owns transactional email templates and renderers using React Email.
+
+## Non-negotiables
+
+1. New email must be added to `src/registry.ts` (`EMAIL_TEMPLATE_RENDERERS`) or dynamic inclusion/discovery will miss it.
+2. New email renderer must be exported from `src/index.ts`.
+3. Renderer contract: async function returning `{ html, subject }`.
+4. i18n namespace must match locale filename in `src/locales/<lang>/<namespace>.json`.
+5. Reuse shared primitives in `src/components/*` for layout/style consistency.
+6. Include one clear CTA and a plain URL fallback in body copy.
+7. Keep subject/body concise, action-first, non-spammy.
+
+## When adding a new email
+
+1. Add template in `src/emails/*.email.tsx`.
+2. Add locale file in `src/locales/en/*-email.json` if template uses i18n.
+3. Export template renderer from `src/index.ts`.
+4. Add renderer to `src/registry.ts` (`EMAIL_TEMPLATE_RENDERERS`).
+
+`src/registry.ts` is required for dynamic inclusion/discovery. If not added there, dynamic template listing/rendering will miss it.
