/* ==========================================================================
   DXTR — public marketing site
   One stylesheet for index / privacy / terms / support.

   Aesthetic: lab instrument. Machined hairlines, monospace data readouts,
   coordinate-frame margins. Dark-first, fully theme-aware (system + manual
   toggle). Boldness is spent in exactly one place: the hero anagram readout.

   Brand system (canonical): primary #F03C00, indigo #3800F0, lime #DEFF24,
   error #E5484D. Martian Mono = display / labels / numbers (restraint);
   Geist = body. Pipeline "three-actor" content colors (HUMAN/OBJECT/ROBOT)
   are semantic to the pipeline and deliberately distinct from the brand trio.
