   My School App — one adaptive stylesheet.
   Mobile (≤767px) is the reference experience. Tablet gets a
   side rail, laptop+ a permanent sidebar, ≥1360px a context
   panel. Same DOM at every size — CSS decides the layout.
   Breakpoints: 768 (tablet) · 1024 (laptop) · 1360 (context
   panel) · 1440 (desktop) · 1920 (ultrawide).
