/* ============================================================================
   THE PEOPLETECHREVOLUTION.COM SITE HEADER.

   Reproduced from what https://peopletechrevolution.com RENDERS (component
   source: ptr-website-html public/TopNav.dc.html plus the shared ring in
   public/ptr-motion.css, origin/main e34cfd18). Every value below was read
   from the live site's computed styles on 2026-09-29 at 1440x900 and 390x844
   and is pinned as data in tests/test_web_assets.py (PTR_COM_HEADER_SPEC),
   asserted against the BUILT stylesheet, because that is what ships.

   It is a SPEC, not an inspiration: if a value here disagrees with the pin,
   the pin is right. If the live header changes, re-measure it and change both.

   The live component writes most of these values as inline styles; here they
   are classes with the live component's own names. Colour rules carry the
   .ptrTopNav prefix because booking's base.css styles bare `a` and `a:hover`
   (cyan), and a single class would lose to `a:hover` on specificity.

   The site header has ONE look (light), on every live page. It is used in both
   booking themes, exactly as the site renders it.

   FIXED, like the live bar; body carries the matching padding-top per
   breakpoint because a fixed bar is out of flow. Do NOT put overflow-x:
   clip/hidden on html/body: it silently disables position:fixed/sticky
   descendants (see WEB-STICKY-HEADER in siteground-ptrvr-website).

   Font: the live header uses the system stack "Helvetica Neue", Helvetica,
   Arial, sans-serif - no web font, so nothing to self-host and no request to
   any font service.

   the UA rule is restored. :where() keeps this at single-class specificity, so
