{{- /*
  Code block render hook.

  Wraps Hugo's standard syntax-highlighted output in a container with a
  copy-to-clipboard button. Highlighting still honours the site's
  [markup.highlight] configuration because we delegate to
  transform.HighlightCodeBlock, which reads both the per-fence options and the
  global config.

  Progressive enhancement: the button is rendered with the `hidden` attribute
  and is only revealed by site-scripts.html when JavaScript runs, so sites
  without JS show no inert button. The copy behaviour itself is wired by the
  same script (a single delegated listener).

  Disable site-wide with `[ananke] copy_code = false` (see params.toml).
