/* ============================================================
STUDENT WEBAPP — Athulya's dashboard
============================================================
Sprint: BTX-MOCKUPS-V3-WEBAPP-001 (BMW3-T10)
Architecture: real product feel — no mockup chrome (no doc-head
with persona tabs, no PRE-APPROVAL pill, no narrator copy).
Imagine: student logs in → lands here. Topbar shows their identity,
sidebar is real product nav, main panel shows their actual data.
Mobile-first: sidebar collapses below 900px per Stage 5 Q4.
