/* ==========================================================================
   Quillo — the design system.

   One stylesheet for every signed-in surface (journal, context graph) and for
   the two doors into the product (sign-in, invite). apps.css layers on top of
   these tokens, so every token name here is a public contract: add, never
   rename.

   The instincts it holds to:
     · calm, editorial, paper-like — hairlines and air do the separating
     · one type family (Inter), a real scale, one measure for body copy
     · Montserrat is the wordmark face and nothing else
     · colour means something: kind of node, overdue, live, connected
     · one obvious subject per page; support recedes rather than competing
     · every colour is a token, defined light on :root and re-tinted for dark
