Standardized code-block Copy & Download buttons

Every code block — on the page, in the file-tree modal, and in OpenAPI request/response samples — shares one Copy and Download affordance, so the interaction is identical everywhere a reader meets code.

Two details worth knowing. The buttons are revealed on hover and on keyboard focus, and a copy announces itself through the page’s ARIA live region rather than only flashing a checkmark. And what lands on the clipboard is the block’s real source: a highlighted or Twoslash-rendered block copies the code, never the type popovers and per-line markup drawn over it. The download’s file extension follows the fence’s language, falling back to .txt for a language it doesn’t recognize.
