// Command build runs the example's full pre-compile step once: directive codegen,
// Tailwind, the wasm binary, and Go's JS shim.
//
//	go run ./build      # from go/cmd/kjol-web
//
// For day-to-day work run the dev server instead (`go run ./server`) — it performs
// these same steps on every save and hot-swaps the result into the browser. This
// command is for a cold build, CI, or an editor's pre-launch task.
