- tools/server/: Node.js dev server (Express + WebSocket + fs.watch)
Watches themes/ for .tmpl changes, rebuilds via Go preview command,
applies Juice CSS inlining for email client compatibility, pushes
live reload to browser via WebSocket.
- tools/cli/dev.go: 'go run . dev' subcommand — starts Node.js server
with automatic npm install, initial preview generation, and
Ctrl+C graceful shutdown.
- tools/tools.go: register dev command in CLI app.
- .gitignore: add node_modules exclusion.
