   PM UNIVERSAL HEADER — css/pm-nav.css  (2026-09-10)
   The ONE stylesheet for the site header. index.html links it (its inline copy is gone)
   and js/pm-header.js injects it on every other public page, so a change here — font,
   colour, the logo/signature layout, the pill — lands everywhere at once.
   Caleb: "the header that we have on the landing page should be universal everywhere".
   Everything is scoped to #nav / .nav-* so inner pages' other <nav> elements are untouched.
