/* DEMO-2 -- BelajarLand public Gateway (`/`). Literal color values
   throughout, not `var(--custom-property)` -- matching student-login.css's
   own documented precedent (a real, reproduced bug where CSS custom
   properties declared in a linked stylesheet silently failed to resolve in
   this project's headless QA browser build). This file is small and
   self-contained, so there is no meaningful maintainability trade-off. */
