/* ==========================================================================
   Refract — Meter
   An image API presented as a live operations console. Near-black floor, ONE
   voltage of acid lime, one alarm red that is a state. Figures in tabular
   monospace that resolve on connect and hold. No paper, no light band, no
   shadow, nothing rounds past 6px. Every figure traces to content.md.
   Shared across this bundle's three pages only.
