/* Shared IT Help Desk theme tokens and reusable lab widgets.
 * Loaded once, before the per-module it-support-module-0N.css files, which
 * consume the --its- custom properties below. Every widget class here is
 * prefixed itsw- (IT Support Widget) so it can't collide with any m0N-/its0N-
 * module-scoped class. This is the one deliberate exception to the
 * codebase's per-module CSS isolation convention — the Module 1/2 lab specs
 * explicitly call for building the evidence-upload and ticket-queue
 * interactions once and reusing them (Modules 1, 2, and 12).
