   Snapport — spec-sheet / calibration-booth theme.
   Paper white + ink + a single electric-indigo signal, Hanken Grotesk
   for type and Geist Mono for every measurement / field label. The visual
   language is a precision instrument: graph grid, ruler ticks, crop guides
   and registration-mark corners. Deliberately unlike a rounded, playful or
   dark UI — this one reads like a calibration sheet.
