   OnLearn — Elevation layer (loaded AFTER app.css, app-wide via base.html).
   Refines the existing design system toward a cinematic, spacious, Kaya-inspired
   feel — fully-rounded pills, softer cards, larger tighter display headings,
   a richer ambient aura, and a shared scroll-reveal + count-up mechanism — while
   keeping OnLearn's violet→cyan identity and every existing component working.
   Additive only: no component is removed, only refined.
