   A single dark, normally-scrolling page: full-height hero with the
   edge-network canvas, a 3-pillar "why" section, the grid-aware
   pricing tiers, and a closing CTA band. Shared primitives (buttons,
   tags, headings, points) come from base.css; sections carry
   .theme-deep so those primitives pick their dark variants.
