/* ==========================================================================
   bans.mowden.top - admin dashboard

   Design direction: "instrument panel". The subject is a shared ban ledger,
   and its native vernacular is addresses, CIDR masks, jail names and sequence
   numbers - so monospace carries the data and a compact grotesk carries the
   chrome. Surfaces are cool and quiet; the only saturated colour on the page
   belongs to data marks and status.

   Chart colours are the validated data-viz palette (blue / orange categorical,
   single-hue blue sequential ramp), checked against these exact surfaces.
