   ECONOMIC TWIN — public site stylesheet
   Identity: "survey sheet" — a night chart-room: warm-black ground,
   paper ink, surveyor's amber, ruled sections, crop-mark corners,
   mono coordinates. Hand-rolled; no framework; fonts self-hosted.

   BRAND SWAP: the wordmark string lives in the HTML ("Economic Twin").
