	2	* Block L2 — one-command install.
	3	*
	4	* GET /install -> the bash installer (scripts/install.sh).
	5	*
	6	* Curl-able: `curl -sSL https://gluecron.com/install \| bash`.
	7	*
	8	* The script is read from disk once at module load and cached in memory; we
	9	* also serve it with `Cache-Control: public, max-age=300` so any CDN in front
	10	* of us can absorb the load. Mirrors the static-string pattern used by
	11	* `src/routes/pwa.ts`.
