   Ignjatov — izrada i dizajn sajtova  ·  v6 "Night Plume"
   Night-teal canvas with a living aurora (WebGL, js/aurora.js),
   alternating with warm paper panels. One system font (SF Pro / Inter)
   throughout. Signatures: blur-in reveals, frosted glass cards
   floating over drifting colour clouds, a rotating conic halo
   around the live demo frames, film grain on everything.
   Transform/opacity motion only.
