/* ---------------------------------------------------------------
   DK Enterprise brand system v2 — professional, modern, "techy" SaaS look.
   Single source of truth for color, type, motion, and component
   styling so every page — marketing, docs, legal — looks like one
   product. Most upgrades here are additive to classes already used
   sitewide (.card-elevated, .section-eyebrow, .hero-gradient, i.bi,
   etc.), so they cascade across every template automatically.
