/**
 * eFit Tracker Connection Wizard
 *
 * Builds on the helpdesk design tokens (helpdesk.css) and the eFit brand
 * family from dashboard/modules-online/coursera-DESIGN.md (primary #004BB5).
 *
 * WCAG 2.2 AAA palette, every pair verified at >= 7:1 with a contrast
 * script during the 2026-08 redesign:
 *   body ink        #1f2937 on #ffffff          14.68
 *   helper ink      #4b5563 on #ffffff           7.56
 *   primary btn     #ffffff on #004BB5           7.85
 *   link on white   #004BB5 on #ffffff           7.85
 *   info ink        #003a8c on #e0f2fe           9.22
 *   success ink     #064e2b on #d1fae5           8.68
 *   warning ink     #6b4700 on #fef3c7           7.46
 *   danger ink      #7f1d1d on #fee2e2           8.20
 *   hero text       #ffffff on #0b2e93..#1b47c2  7.70 at lightest stop
 * Status is always icon + text (1.4.1). Targets are >= 44px (2.5.5
 * Enhanced). Focus is a 3px ring with offset (2.4.13). Motion honors
 * prefers-reduced-motion.
