// Runs before the server starts, so changing the emoji only requires a restart
// — no rebuild.

// The output directory is passed as the first argument (relative to cwd):
//   - prod (`deno task start` / `serve`): `dist` — what the Oak server serves
//   - dev  (`deno task dev`):             `public` — what the Vite server serves
// Defaults to `dist` when omitted.
