/* ====================================================================
   Plexxa marketing — shared styles for subpages (about, contact,
   privacy, terms, DPA, security, etc.). The home page (index.html)
   keeps its own inline CSS because it has lots of bespoke product
   visuals; this stylesheet is the common shell — design tokens, top
   nav, footer, content body typography, and a long-form prose layout.

   Tokens match the home page exactly so the brand carries through.
   Dark gradient hero at the top of each page, clean white body for
   long-form reading.
