/* Parcel Command Center — executive monitor
   ────────────────────────────────────────────────────────────────
   The identity comes straight from the logo, which is exactly two colours,
   sampled from parcelLogo.png rather than guessed:

     navy   #09273D   the wordmark    — structure, body text, primary actions
     amber  #FED12C   the parcel box  — the single highlight

   Light mode makes navy the accent, because amber on white is unreadable.
   Dark mode inverts it: the ground becomes the navy family and amber becomes
   the accent — which is the logo's own pairing.

   Semantic colours are kept deliberately clear of brand amber: warning is a
   desaturated orange-brown, so a status pill can never read as a brand mark.
