/* TradeInSyria — pre-launch landing page
   Brand Board v1 tokens. RTL-first: every spatial rule uses logical
   properties, so the Arabic page needs no separate stylesheet (R-172).

   Fonts: system stack here. The platform proper self-hosts and subsets
   Cairo per R-175 — deliberately NOT loading from a font CDN, which would
   disclose every visitor's IP to a third party. */
