+Mobile-first email template and report builder for Arrowstack applications.
+
+## Current MVP
+
+- PWA designed from 320px upward
+- tap-to-add and tap-to-edit block workflow
+- local IndexedDB draft persistence plus debounced server autosave
+- report and email template profiles
+- sample JSON data and variable bindings
+- MJML email rendering
+- HTML and A4 PDF report rendering
+- immutable publish versions
+- server-side Keycloak OIDC authorization-code + PKCE flow
+- PostgreSQL persistence
+
+## Local development
+
+Copy `.env.example` to `.env`, provide a PostgreSQL database, and leave `AUTH_REQUIRED=false` for local-only development.
+
+```bash
+npm install
+npm run dev
+```
+
+The production deployment uses Arrowstack MCP to inject `DATABASE_URL`, `KEYCLOAK_ISSUER`, `KEYCLOAK_CLIENT_ID`, and `KEYCLOAK_CLIENT_SECRET`. Never commit real credentials.
