  US-002: Prominent install CTAs in hero (PRD AC + critique P0).
  Reuses .cs-grid-2/.cs-card/.cs-code-wrap inside .cheatsheet-hero for dense cheatsheet consistency.
  Minimal extension: sharp rect (per DESIGN), dashed border, tokens, top-level visibility.
  .install-hero wrapper provides breathing + "meu fluxo" signal without new components.
  Extends existing hero/TOC rhythm + responsive media queries. No conflict with elevation or body cs-*.
