/* AL QOBA AL ZAHBIA — prismatic light through obsidian.
   Marketing pages (home, contact, company) run on the brand's near-black navy with
   one near-white ink; authority comes from scale, never weight. Colour belongs to
   the brand artwork alone — the interface stays monochrome. Legal pages keep the
   light reading theme. No shadows anywhere: hairlines and scale carry structure. */
