   Arabic Guide: British Museum — marketing landing page (V1 candidate)
   Shared stylesheet for the Arabic (/) and English (/en/) pages.

   Deliberately uses CSS logical properties (inline-start / inline-end /
   text-align: start) so one stylesheet renders correctly in both RTL and LTR.

   No third-party requests, no fonts loaded from a CDN, no analytics.
