/* The site's colours and faces: the landing page at / and the manual at /docs/ (WP-2021).
   This file is their one authority.  `build.py` inlines it at the top of the landing page's
   stylesheet; the manual's `conf.py` copies it into `_static/` and loads it before
   `custom.css`, which maps pydata-sphinx-theme's `--pst-*` names onto these and spells no
   colour of its own.  `docs/landing/README.md` § House style says which colour does which
   job, and `tests/test_landing.py` measures every text colour against every ground it is
   drawn on (WCAG 2.2 AA, 4.5:1).

   Written three times: light on `:root`; dark when the system asks for it and no light theme
   is pinned; dark when pinned.  The two dark blocks are one set of values, held equal by the
   same test.  Both pages pin a theme through `data-theme` on `<html>`, and pydata also
   writes `auto` there before its script resolves it, which the second block reads as the
   system's choice. */
