   TrueDo web app — MONOCHROME dashboard theme + motion (app.html only).

   marketing pages / finance.html keep their colored theme.
   Design language: complete black & white. Dark = true black canvas, white
   ink. Light = paper white, black ink. Hierarchy comes from grayscale steps,
   weight and motion — never hue. Matches the phone app's monochrome Tasks.

   CTAs, purple reserved for charts. Dark = equally-flat near-black. Hierarchy
