/* ==========================================================================
   TreeListView documentation - the treelistview.com/docs chrome
   ==========================================================================
   Loaded after docs.css, by the pages in deploy/docs-tlv/ only. docs.css
   styles the content and the layout for both builds; this file adds what the
   binarymission.co.uk build takes from the site's site-shell.css instead: the
   ten theme palettes, and the docs' own header, theme select and footer.
   Nothing here may be needed by deploy/docs/, which does not load it.

   Same ten palettes, same `html[data-theme]` selectors and the same
   `bm-theme` key as treelistview.com. --text-faint and --accent-ink are the
   main site's values, which clear 4.5:1 on these backgrounds.
