   Layout: one left-aligned 1180px column, hairline rules, long quiet sections; the single bold moment is the hero chart.
   Colour carries meaning: each system has one hue, benchmarks are grey, the UI itself stays neutral.
   Tokens come from the dashboard design system (ui/style.py): ink #0C0D10, panel #101216, text #ECEAE3, cyan accent. */
