   Dark, sleek, minimal. White text on black; one calm accent (teal) carries
   hierarchy and interactive cues, everything else is tonal. Built to
   WCAG 2.1 AA: every text color pair here clears 4.5:1 contrast (most clear
   AAA), focus is always visible, motion is opt-out, and the layout reflows
   cleanly down to small screens.
