Summary Add a small “Copy” button to every code block (…) across documentation pages (including installation guides). The button copies the code to clipboard, gives immediate visual feedback (e.g. “Copied!”), is keyboard accessible, and works for dynamically rendered content (client-side navigation). Use progressive enhancement (works if JavaScript is enabled; if not, code remains readable). Why Improves developer DX: copying long commands / snippets is tedious without a one-click button. Standard expectation for docs & reduces copy/paste errors. Accessibility-friendly copy affordance helps keyboard & screen-reader users. Proposed solution* Add a small Vue 2 client-side enhancement that: Finds all blocks and inserts a copy button. Uses the modern Clipboard API with a robust fallback. Shows visual feedback (tooltip text changes to “Copied!” then reverts). Supports keyboard activation and has appropriate aria- attributes. Handles dynamically inserted code blocks (MutationObserver). Minimal CSS to match docs styling. Add a single small global CSS file for the copy button. Add tests/manual checklist.
