// - dev: builds the site and serves it. JS and CSS changes can be picked up
// with a reload.
// - build: builds the site and writes it to dist/
// - serve: serves the site from dist/ (embedded in the binary)

tsconnect implements development/build/serving workflows for Tailscale Connect.
It can be invoked with one of three subcommands:
- dev: Run in development mode, allowing JS and CSS changes to be picked up without a rebuilt or restart.
- build: Run in production build mode (generating static assets)
- serve: Run in production serve mode (serving static assets)
