/* ============================================================================
   MINDPHASE — product pages
   ============================================================================

   The app's own look, not the studio's: the same rule that keeps /spora in
   Spora's voice. Graphite ground, paper ink, hairlines, light type, one
   letterspaced wordmark. No fills, no gradients inside anything — only the
   faint pool of light the app puts behind its objects.

   Every page under /mindphase links this and nothing else.
