/*
  The login page's styles, in a file rather than an inline block, because the
  service serves everything under `style-src 'self'` (spec §3.5) — there is no
  `'unsafe-inline'` anywhere, so an inline block would simply not apply.

  Checked in, unlike app.css, which deploy/dash/build.sh produces. Same tokens
  as app.css, cut down: this page must keep working when the bundle is
  unbuilt, so it shares nothing with it but the palette — and the faces,
  which both pages take from /fonts.css.
