   Stats Cram Cohort — landing page
   Concept: "The Distribution." The page is a coordinate plane; the student
   travels from the shaded fail-tail to the green pass-region where the CTA lives.
   Palette: graph-paper ground, ink navy, exam-red (reject), confident green (pass).
   Type: Space Grotesk (display) · Space Mono (data/labels) · Inter (body).
