/* =====================================================================
   ALJEBRAL ADVISORY — V2 site.css
   Phase 1 (structure only). Base/nav/hero/practices/footer rules reused
   verbatim from the live site's design system (same tokens, same
   palette/type/radius/gold rules). New rules cover the six-section V2
   layout: workflow-diagram placeholders, tool/system toggle, case
   pager, process steps, and the two-column contact section.
   Component build (real scroll mechanics, real videos) is parked —
   see V2 site revamp/v2 aljebral site revamp.md Phase 2+.
