Pull request overview

This PR fixes the copy button in the legacy-html generator so it is hidden when JavaScript is disabled (via the existing :root:not(.has-js) CSS pattern). It also adjusts the layout so the button moves to the bottom of the code box, aligning with previous tooling behavior.

Changes:

• Adds a CSS rule to hide .copy-button when the has-js class is absent from :root
• Removes float: left from pre > code to allow the button to render below (rather than beside) the code content
• Adjusts .copy-button margins: removes margin-top: -2px (no longer needed) and converts margin-right from 10px to 0.2rem
