/* ==========================================================================
   Student Project Hub — /student-projects
   --------------------------------------------------------------------------
   Layered on top of premium.css (tokens + buttons + headings),
   gis-experience.css (dark canvas overrides + reveal) and gis-3d.css (3D
   scenes). Nothing here redefines a token; the hub only adds its own layout.

   Every glass surface below carries an OPAQUE background colour. The ambient
   particle canvas sits behind the content at z-index -2, so a translucent
   card drops body text to roughly 1.15:1 against moving pixels. Opaque base +
   translucent tint keeps the depth without destroying legibility.
