   VeriPhy Health — shared stylesheet for all sub-pages (security/about/contact
   and the coming content pages). Extracted verbatim from index.html's design
   system (ocean-teal palette) so every page renders identically, then extended
   with .prose / .breadcrumb / .diagram / .tbl utilities for article pages.
   NOTE: index.html still carries its own inline copy of the base rules — leave
   that page untouched; migrate it to this file later as a deliberate step.
