   onega.dev · product tour design: the /oneai/ design system, shared by the
   OneDesk and OneMail tours. Dark ground #0e0a12 with alternating light
   chapters, a blueprint-grid hero with the fold sculpture, drifting isolines,
   labelled traces into an animated schematic, panels and interactive demos.
   Copied from the OneAI tour stylesheet; site additions are at the end.
   No inline styles: every variable the OneAI page set inline is a class here.
