   Shared site header/nav. Loaded by every subpage so the header is identical
   sitewide (the homepage carries the same rules inline in index.html — keep
   the two in sync). Desktop: logo left, links centre, Book-a-call right.
   Mobile (<=900): burger (left) · logo (centred) · calendar-icon CTA (right),
   with the page links in a terminal-window dropdown the burger toggles.
