   Palette is taken straight from the logo: navy #042152 (the wordmark)
   and orange #FA6507 (the highlight). Navy carries the interface —
   chrome, headings, primary actions. Orange is the emphasis colour:
   active states, price figures, badges. Used sparingly, as in the mark.

   Type is IBM Plex — a corporate family with matched Sans and Mono, so
   figures in tables line up with the prose around them. Self-hosted in
   assets/fonts, no third-party requests.
