	2	* Gluecron core flow load test
	3	*
	4	* Tests the main public-facing pages under sustained load.
	5	*
d8cf368Claude	6	* THIS FILE RUNS UNDER k6 — do not run with node or bun directly.
	7	* k6 provides its own built-in modules (k6/http, k6/metrics, etc.) at runtime.
	8	*
3122762Claude	9	* Usage:
	10	* k6 run scripts/load-test.js
	11	*
	12	* Override base URL:
	13	* BASE_URL=https://gluecron.com k6 run scripts/load-test.js
	14	*
	15	* Staged run against staging:
	16	* BASE_URL=https://staging.gluecron.com k6 run scripts/load-test.js
	17	*
	18	* Requirements: k6 >= 0.46 (https://k6.io/docs/get-started/installation/)
