   CellScope Pro — skin v7 "Studio"  (2026-06-12)
   The definitive professional white workspace. Loads after v2–v6 and settles
   every visual argument with one coherent design system:
     chrome #f8fafc · surface #fff · hairline #e2e8f0 · ink #0f172a
     accent indigo #4f46e5 · ok #059669 · warn #d97706 · bad #dc2626
   Desktop-software density: 13px base, 26px rows, 30px toolbar buttons.
