/* Isocenter docs site: the "clinical ledger" system (#350), on
 * pydata-sphinx-theme.
 *
 * Warm off-white ground, one muted teal accent, Newsreader on headings,
 * Source Sans 3 body, JetBrains Mono code (all three loaded from Google
 * Fonts by docs/conf.py's html_css_files). The design canvas this
 * implements is the "Isocenter Docs Site" artifact; the values below are
 * lifted from it, and were the MkDocs site's docs/stylesheets/extra.css.
 *
 * The fourteen --ledger-* tokens are the system; pydata's --pst-* variables
 * are mapped onto them, then the few places pydata draws with something
 * other than a variable (the header's shadow, the admonition's coloured
 * title bar, code blocks) are restyled against its .bd-* classes. The site
 * is light only (D7), so the mapping is scoped to the light theme, the only
 * one conf.py lets a reader choose.
