/* blobs.com — one stylesheet for every page and language.
   Ported from Codex's approved homepage (Blobs_Dev_Marketing/official-website/v006/homepage.css): same cream
   paper, ink outlines and blue accent. Added: logical properties so Arabic mirrors correctly, the language menu,
   the footer's link and social columns, and the legal, contact and not-found pages.
   No external fonts: the system's own faces, so the site loads nothing from another company. */
