/* Vortex design tokens, shared by the builder and the panel.

   Language: spatial UI. Frosted instrument panels float over the camera feed
   and the blocks are lit cobalt tiles. Every panel carries a solid-enough
   scrim that its text passes AA over any webcam image, because the ground
   behind it is somebody's room, not a colour we chose.

   Three role colours, used identically in CSS and on the HUD canvas:
   build (azure), erase (coral), rotate (amber). Everything else is a neutral
   leaning toward the block blue. */
