/*
  The Chrome theme's shape: Google Drive's type, spacing, pills and rounded
  surfaces. Chrome is the default, and its colours are the default token
  block in themes.css. The root layout renders data-ui-theme="chrome", so
  this applies before any choice has been saved.

  Everything here is scoped to the theme, so no other theme sees any of it,
  and it styles the workbench only: documents keep the fixed typography in
  viewer.css, because a theme must not change content.
