   ───────────────────────────────────────────────────────────────────────────
   Landing-only styling of the shared header. navigation.css (shared with the
   inner pages) loads first and keeps the structure, colours and the TOS
   dropdown; this file turns the bar into the floating pill, adds the
   hide-on-scroll state that landing/nav.js drives, the phone menu that the
   shared mobile-header.js toggles, and the fixed scroll-progress bar.

   Selectors keep the `.landing-atmosphere` prefix so they outrank the shared
   rules by specificity, not only by load order. The pill's background stays
   at (0,2,0) so render-mode's `html.gpu-lite .site-nav` (0,2,1) still wins on
   software renderers.
