/* ═══════════════════════════════════════════════════════════════════════════
   LegalStep.ai — design system.

   A deliberate break from the LegalCollect "ledger" identity. The organising
   idea: an MCP server is a *surface of named, bounded tools*, so the page is
   built around the permission taxonomy the product actually enforces —
   reads / writes / guarded. That taxonomy colours the hero trace and
   classifies every capability. Nothing else is colour-coded, so the code
   always means the same thing.

   Loaded by every page on this site. assets/theme.js handles the light/dark
   toggle; the LegalCollect wordmark SVGs appear in the footer lockup.
