   aRTCo Tax public header system

   - marketing: full navigation for index, about, pricing, and data flow
   - document:  compact logo + login navigation for legal and policy pages

   The homepage keeps its photographic-hero overlay behavior in index.html.
   Other marketing pages use the shared solid/sticky treatment below.
