/* The admin portal, in the look of Diveology's and Bauernschnapsen's: a dark sidebar with the mark and an Admin tag, a
   pale work area, white cards with round corners and a soft shadow, round-ended buttons, the device's own font. My
   Empower's colours: forest for the sidebar, field green as the accent (lime in dark mode). Every colour is a token
   here; dark mode follows the device and redefines them, so a new colour goes in both sets. */
