   Soft slate-blue base (#0f1a2b) + operational green (#1a9e5c) accent. Roboto +
   Roboto Mono. Dark is the DEFAULT (:root); [data-theme="light"] swaps to light.
   Colour means status. Calm, credible, non-technical.
   Defines: (1) the dashboard classes from the design mockup, and
   (2) the legacy auth/admin classes so those pages inherit this palette.
