   Design notes
   ------------
   Palette is drawn from the app icon: a neon brain split coral (left) /
   cyan (right) on near-black. Those two hues carry meaning throughout:
       coral  = you, and the decisions you keep control of
       cyan   = the AI and the scheduling algorithm
   Neuro-ergonomic intent: one idea per section, generous rhythm, type
   picked for legibility (Atkinson Hyperlegible), motion only where it
   means something, and full support for Reduced Motion and both themes.
