	2	* Block L3 — public /demo page + JSON endpoint smoke tests.
	3	*
	4	* Exercises route status codes + content-type + cache headers, plus the
	5	* pure-helper behaviour of the activity module (returns `[]` on DB
	6	* unavailability) and idempotency of `ensureDemoActivity()`.
	7	*
	8	* No DB writes from the test — when the test process has no usable
	9	* `DATABASE_URL`, the helpers fail-soft and we assert that they still
	10	* return shaped data rather than crashing.
