   Cogniscan marketing site: homepage (#landing-screen), /request-demo.html
   and /assessments.html. Everything is scoped to `.site` so it cannot leak
   into the clinician app screens that share index.html.

   World: the faceplate of a precision measurement instrument. Warm-grey
   housing (graphite in dark mode), engraved labels, recessed glass readouts
   that stay dark in both themes, binary LEDs, physical keys with travel, one
   royal-blue key. Motion is stepped or linear, never floaty.

   Theme: light housing by default, graphite when <html> has `.dark` (set
   before paint by the inline script in each page head).
