/* Shared site footer, written into every page by .github/scripts/site-footer.py.
   It takes the page's own font and text color, so it fits every app's look.
   A page can tune it by setting any of these on body or a wrapper:
     --sf-bg     background (default: none)
     --sf-text   text color (default: the page's)
     --sf-line   divider color (default: text color at 15%)
     --sf-max    content width (default: 1120px) */
