   Site header and footer (Views/Partials/Shared/Header.cshtml and Footer.cshtml)
   Loaded on every page by Views/Layout.cshtml, in the old design and the 2026 redesign alike.
   Everything is scoped to .pc-chrome (the header, the phone menu and the footer) with its own
   pc- class names and colour tokens, so the old design's styles and variables never reach it
   and it never changes theirs. Behaviour: scripts/shared/header.js.
