/* RedRoom Legion Plugins
   The label is a dark room with one red light in it; each plugin brings its own colour into that room
   (the Liminal series: the amber of its knob arcs). Flat surfaces, one typeface, motion that settles.

   Tokens
   colour   --base #000, surfaces #181818 / #1F1F1F / #272727 / #313131, --ink, --muted, --dim, --legion (label red),
            --accent (set per page: legion red on the hub, amber on a Liminal page)
   type     Geist for everything; Geist Mono only where digits must line up (versions, sizes, specs)
