/* --- Keep the copy button reachable on tall code blocks ---------------- */
/* sphinx-copybutton pins the button (`position: absolute; top`) to the top of
   its code block, so on a block taller than the viewport — e.g. the long C++
   sample under group functions like cv::imwrite — it scrolls out of sight the
   moment you read past the first lines, and the whole button looks "missing".
   Make it `position: sticky` so it rides along at the top-right of the visible
   area instead. Hover-reveal behaviour is untouched (no opacity change); the
   button is still a child of `.highlight`, so `.highlight:hover .copybtn` still
   fires.
   Sticky needs NO non-`visible` overflow between the button and the scrolling
   viewport (the window). Two ancestors set overflow and silently disabled it:
   the member-detail card (rounded-corner clip) and the theme's
   `.bd-article-container`. Neither actually scrolls — the window does — so
   relaxing them is safe; the secondary "On this page" TOC stays sticky
   (verified). `display:flex` + `order:-1` put the button above <pre> in flow so
   `top` has something to pin to; the negative bottom margin cancels the
   button's own box so it overlays the code instead of pushing it down. */

 * repaints them lighter (or grey, or visited-purple) in dark
 * mode through dozens of class-specific rules. Rather than
 * chase each one, this final block forces every `<a>` (and
 * every descendant of `<a>`) inside `html[data-theme="dark"]`
 * back to the same `#0969da` link blue used in light mode —
 * body content, sidebar, TOC, tables, code chips, code-block
 * tokens, See-Also lines, breadcrumbs, footers. Visited /
 * hover / active / focused all collapse to the same hex per
 * the "no hover-blue, everything at rest" rule.
 *
 * Specificity: `html[data-theme="dark"] a` is (0,0,1,2); the
 * `* { color: unset }` rule earlier in the file is (0,0,1,2)
 * too but ours runs LATER and uses `!important`, so it wins.

/* Pygments-tokens-inside-link override.

 * { color:#cdd9e5 !important }` (3-class specificity) was beating the
 * global `html[data-theme="dark"] a *` rule above (1-class) when a
 * Pygments identifier span (`.n`, `.nc`, `.nf`, `.na`, `.nb`, `.nv`,
 * `.nn`, `.pre`) sat inside an `<a>` — so enum-synopsis entries like
 * `cv::NORM_INF` rendered the same grey as plain identifiers. Adding
 * `.highlight` to the selector raises specificity to (0,0,3,2),
 * enough to win on every token class Pygments uses for names. */
