/* ============================================
   FINO — Shared site navigation
   ============================================
   Standalone component for pages that carry their own inline style
   system (self-led-ai-integration, projects/law-firms, studio) and do
   not load style.css. Every value is explicit rather than inherited,
   so a host page's :root cannot shift it. Deliberately avoids .btn and
   .container, which those pages already define.
