/* SkillSync Infinity: enhancement layer, loaded after site.css.
   Adds motion and depth to the existing design without changing its fonts,
   colours or layout. Ported ideas: Aceternity UI (spotlight, moving border,
   glowing card edges, background beams, tracing beam), 21st.dev (dithered
   wordmark, spotlight comparison), Codrops-style clip-path image reveals.
   Everything is decoration: the page reads the same with it switched off. */
