/*
  Shared layer for w9w6.com and rent.w9w6.com: fonts, tokens, page frame, header,
  footer, buttons. Each site adds one stylesheet of its own (hub.css, rent.css).

  Rules kept from the original site:
  - animate transform and opacity only;
  - logical properties (inline/block), so the Arabic pages mirror with no extra CSS;
  - no client-side JavaScript: the language switch is a link, and the cross-page
    fade is a CSS view transition.
