/* YTE G13 public homepage — redesign directions (Issue #8).
   Two compositions share one component system:
     .dir-a  "Official YTE Innovation Portal" — editorial, institutional
     .dir-b  "Youth Innovation Live"          — video-forward, energetic
   The public homepage is served without the authenticated CSP, but every asset
   here is still local, and no inline event handlers are used. */
