/*
  3DT GUI - the one common stylesheet for every page shown in the GUI's
  content frame. Two page types share it:
    - map page      (.map-page): full-bleed Leaflet map + right-hand panel
                    (CIRCUITS > TRACK LIBRARY, CIRCUITS > WHITELINE EDITOR)
    - content page  (CONFIG > ONBOARD): panel without a map
  A page keeps only what is truly its own (map markers, special widgets).

  Colours: never written here as values. Layer 1 is the official palette
  (colors.css); layer 2 below gives each colour its ROLE. To restyle, change a
  colour in colors.css, or point a role at another palette colour here.
