   demo.css — stilovi za Aling klikabilan demo (S119)

   Ponašanje:
   - DemoLanding reuse-a `.login-shell/.login-hero/.login-form-wrap` iz login.css
     (isti split layout, ista tipografija, isti Pine/Orange brand).
   - Ovaj fajl dodaje samo demo-specific elemente: primary CTA gumb, side-staza
     row (kao list-item, ne kartica), izazovi lista, završna stranica (`/demo/kraj`),
     demo popover (fixed overlay).

   Brand tokeni iz app.css (--brand-primary, --brand-accent, --p-*, --a-*, --gray-*).
   Bez custom boja. Sve kroz postojeće varijable.
