/**
* Copy-to-clipboard icon button for the code header of the @pierre/diffs widgets.
* A faint chip that lifts on hover, presses on click, and crossfades the copy
* glyph into a green check on success.
*
* The widget themes itself off the OS `prefers-color-scheme` (its shadow root
* pins `color-scheme: light dark`), NOT the site's class-based dark toggle, so
* the header can be light even with the docs in dark mode. The chip's colors
* live in the `.diff-copy-button` rule in global.css and use `light-dark()` to
* track that same signal, staying legible on either header. Icon-only; the
* caller positions it (usually absolute top-right).
