   DED TECH — Shared Design System
   Brand blue (#0468C9) sampled directly from the client's logo file.
   Typography: Poppins (display/headings) + Archivo (body/UI).
   Note on fonts: "Franklin Gothic" is a licensed system font not available
   on Google Fonts / the open web. Archivo is used in its place — it shares
   the same DNA as Franklin Gothic (grotesque sans, sturdy, high x-height,
   built for signage/headline clarity) and is the standard open-source
   substitute. Flagging this substitution directly rather than silently
   approximating with something unrelated.
