/* =========================================================
   ZAMAN IT — Design System
   Palette rationale: deep trust-blue for credibility (est. 2008,
   corporate/enterprise clients), a signal-teal for interactive
   "systems online" motifs (nodding to their security/automation/
   uptime-driven services), and a warm amber CTA that pops against
   the cool palette for conversion. A restrained flag-green is used
   only for verification/status ticks — a quiet nod to Bangladesh.
   Swap the --brand-* values below once official logo/colors arrive.
