   Colours are lifted from the app's own Avalonia theme (src/Theme/FidoTheme.axaml)
   so the site and the application read as one thing.

     amber      #F4A62A   the hero button, the flight log's "GO"
     amber-lo   #EF9E1C   pressed
     amber-hi   #F8BA4D   hover

     parchment  #F5F1E8   light surface
     alert      #E06055   destructive actions

   Amber on white is ~1.9:1, so it is never used for body links. Light mode
   links use a darkened amber (#8A5A0B, ~5.6:1 on white) instead; dark mode
   can use the amber itself.
