/* ── Shared chrome for the United Automation web estate ────────────────────
   ONE file, linked by every public page on BOTH zones (hairdocs.no and
   unitedautomation.no). It carries the header, the nav, the cross-domain
   link and the footer — the parts that must be identical for the two sites
   to read as one company.

   ⚠️ It deliberately declares NO colour, type or spacing values of its own.
   Every rule here resolves `var(--…)` against tokens the *page* defines, so
   the tokens stay single-sourced per page (delivery/DESIGN_SYSTEM.md §2–§4)
   and this file cannot become a second, competing palette. A page that links
   this file without those tokens renders unstyled chrome — loud, not subtly
   wrong.

   ⚠️ Loading it at all needs `style-src 'self'` in `_headers`. Both zones'
   `_headers` say so. Drop that and the chrome silently disappears while the
   page content still renders — so the estate gate in
   `test_sales_calculator_static.py` pins the directive.

   ⚠️ This file is served publicly and whole, like everything else in a Pages
   directory (delivery/site-notes.md). Nothing internal goes in it.          */
