/* Module 02 (IT Help Desk) is fully isolated. Every selector is scoped with
 * its02-. Shared evidence/ticket-queue widget classes (itsw-) and color
 * tokens (--its-*) come from it-support-shared.css, loaded first. Labs 2.3
 * and 2.4 are a guided walkthrough in the real simulator (the itsw-evidence-
 * button launch link), not a portal-embedded mini-app — there's no
 * dedicated CSS for them here beyond the shared lab-status indicator. */
