  brinkbar.com — one stylesheet for every page.

  Colors are the branded token set from the Brink brand guide

  the dark set on :root, the light set under prefers-color-scheme: light.
  Headings use the wordmark faces (Bricolage Grotesque, JetBrains Mono, loaded
  from Google Fonts in each page's <head>); body text uses the system font.
