/*
 * Dark-mode bridge for the embedded Doxygen (doxygen-awesome) pages.
 *
 * doxysphinx leaves doxygen-awesome's light variables on the global `html {}`
 * selector but scopes its dark block to the impossible selector
 * `.doxygen-content html.dark-mode`, so the C++ API pages always render with the
 * light palette — white boxes on the dark pydata page.
 *
 * pydata marks dark mode with `html[data-theme="dark"]` (explicit) and
 * `html[data-mode="dark"]` (auto-resolved). Re-declaring doxygen-awesome's dark
 * palette under those selectors makes the variable-driven doxygen styles follow
 * the site theme. These variables only affect doxygen-awesome elements, so other
 * pages are unaffected.
