KenanZhuandClaude 0ad7db124a refactor(preview): remove juice/Node.js, simplify to pure Go dev server with SSE
- Delete tools/server/ (Node.js, juice, inliner.mjs, server.mjs, node_modules)
- Create tools/preview/server.go — pure Go dev server with SSE + file polling
- Rewrite tools/cli/dev.go — start Go server in-process, no Node.js required
- Simplify preview/index.html — View dropdown (Modern/Source), remove Client
  Simulation panel, remove Gmail/Outlook logic, WebSocket → SSE
- Update all 14 documentation files (README, CONTRIBUTING, AGENTS + translations)
  to reflect pure Go dev server and simplified preview

# Contributing to Gitea Mail Templates
Thanks for your interest in contributing! This project aims to provide a diverse, well-maintained collection of email templates for the Gitea ecosystem.

## Ways to Contribute
### Adding a New Style
1. Scaffold the new style: `cd tools && go run . create <your-style-name>` — this creates the directory structure with placeholder `.tmpl` files for all 11 email types
2. Edit each `.tmpl` file in `themes/<your-style-name>/` with your unique visual design
3. Regenerate the preview: `cd tools && go run . preview all` — the build script auto-discovers all theme directories under `themes/` and generates the theme selector dynamically
4. Submit a PR with screenshots of rendered emails (≤ 50 KiB each, 10–20 KiB recommended)
### Style Guidelines
- Each style must include **all 11 template types** listed in the README
- Use only Gitea's built-in template functions — check the [Gitea source](https://github.com/go-gitea/gitea) for reference
- Translation keys must come from Gitea's official locale files (`mail.*` namespace)
- **Never reference `.DisplayName`** in templates where the data context lacks it (collaborator, transfer, release, workflow_run, assigned, default)
- Design for 600px max-width email clients
- Test against major email clients (Apple Mail, Gmail, Outlook) when possible
### Bug Reports
If a template doesn't render correctly:
1. Check that all referenced Go template variables exist — compare against the Gitea source mail templates
2. Verify translation keys match Gitea's locale files
3. Confirm `.DisplayName` isn't used in templates that lack it
4. Regenerate the preview: `cd tools && go run . preview all`
5. Open an issue with: the style name, which email type, and the error or unexpected output
### Documentation Improvements
Documentation updates, preview screenshots, installation guides, and translations are always welcome.

## Development Setup
- **Go 1.21+** for template rendering and the CLI tool
### Previewing Locally (Static)
1. Run `cd tools && go run . preview all` to generate rendered data
2. Open `preview/index.html` directly in a browser — no server needed
3. Use the theme switcher, template selector, and view mode toggles
### Dev Server (Live Reload)
```bash
cd tools && go run . dev
# → http://localhost:3456
```
- Watches `themes/**/*.tmpl` — auto-rebuilds on save
- Pure Go HTTP server with SSE push — no external dependencies
- Re-renders templates in-process and pushes reload events to the browser
- Terminal output: `themes/aurora/mail/repo/release.tmpl changed` → `[Builder] Rebuild done in 45ms`
### Integration Testing
Deploy the templates to a Gitea instance and verify with real transactional emails.
The admin test email (**Site Administration > Configuration > Mailer > Send Test Email**)
does not use custom mail templates — it follows a built-in code path.
The most reliable method is to trigger a real notification. For example, the password
reset flow:
1. Log out and click **"Forgot password"** on the login page
2. Enter your account email and submit
3. Check the password reset email — it will render with your custom mail templates
