/* LearnHub Student Tabs — v2 (chips + icons)
   ------------------------------------------------------------
   Objectives:
   - Tabs must be independent (no shared background container)
   - Visual parity with the reference UI (active underline + icons)
   - Works both inside .ea-shell-content and as a fallback outside it
