/*
  Select - one stylesheet for the public site, the admin panel and the labels.

  Rules this file follows:
  - Black, white and greys only. (The single exception: amber/red ageing
    badges in the admin queue, because they are warnings, not decoration.)
  - Inter everywhere, self-hosted from assets/fonts. No serif anywhere.
  - Every size and gap is a multiple of 4px (the --s* steps below).
  - Letter-spacing gets tighter as text gets bigger, so large headings do not
    look loose and small labels do not look cramped.

  Sections: 1 fonts & tokens  2 base  3 layout  4 components  5 public pages
            6 chat widget  7 admin  8 slab label  9 print
