/**
 * Generates the favicon set and manifest from the runtime `GERBEUR_SITE_EMOJI`.
 * 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), and
 * defaults to `dist`:
 * - prod (`deno task start` / `serve`): `dist` — what the Oak server serves
 * - dev (`deno task dev`): `public` — what the Vite server serves
