   XLATE Technology — cinematic concept design system (v2)
   Non-production proof of concept.

   This file supersedes css/main.css (kept only as an unreferenced legacy
   copy after a file-sync fault corrupted it; do not link main.css).

   CINEMATIC SECTION LAYER ORDER (explicit z-index, per layer):
     0  .scene-bg          generated Higgsfield still/video backdrop
     2  .scene-canvas      animated Canvas technical graphics
     3  .scene-shade       readability gradient/vignette (pointer-events none)
     4  scene content      headlines, captions, stage labels, CTAs
     50 .nav               fixed navigation, above all page content
   .pin__viewport uses isolation:isolate so nothing inside leaks out of
   this stacking context, and no child creates an accidental one above it.
