/* ============================================================================
   SPEEDRUN — supermega.design/speedrun, the landing for a16z speedrun founders
   (2026-10-27). The site's chrome (header, .btn, Tanker + General Sans, the dark
   footer) on a black page lit by speedrun's own prism: teal, blue, pink, coral,
   amber, green. Building blocks re-engineered from thesis.co (study in
   _ref/speedrun/STUDY.md): the iso plane, the blur-text reveal, stairs, the cube
   field, the numbers grid, slabs that land. Everything here is ours: the plane is
   a shader, not their film; the colour field is generated from the prism.
