   Boulder Biologics — site chrome (2026-10 redesign)
   ============================================================
   Shared by the homepage and any page on the light theme:
   design tokens, pill buttons, the navy header with dropdown
   nav (.site-header.hp-header), and the stone footer
   (footer.site-footer.hp-footer). Selectors are doubled-up
   (.site-header.hp-header …) so they win over the older header
   and footer rules in _v2-service.css / _shared.css and the
   hamburger rules in _nav.css. Load after those files.
