/* Just series web kit: series.css
   One file, byte-identical on every Just site. Do not fork it per app.
   Each page sets its accent on <html style="--accent:...;--accent-dark:...">:
   --accent is used on the light theme, --accent-dark on the dark theme and on the felt header.
   No web fonts, no external requests: the icon is the site's own /app-icon.png. */
