/* ARM conditional execution — Sophie Wilson's ruthless efficiency, made visible.
   To keep the larger of two numbers an ordinary CPU compares, then *branches*; a
   taken branch can flush the pipeline and waste cycles. The ARM instruction set
   Wilson designed lets almost every instruction carry its own condition, so the
   same job runs branch-free: both candidate MOVs are decoded, the condition decides
   which one writes, and the pipeline never stalls. Doing more with simpler, smaller
   hardware is the whole bet. Vanilla JS, no deps, no build.
   Palette shared with siblings: cyan = active/executed, green = the value that wins
   (the win), dim = decoded-but-discarded. No red. */
