Overlays and copy feedback

Menus, lists, tooltips, toasts and the confirm dialog, open, in both colour schemes at once. Pop-overs lift with a soft shadow and a 1px border so they read on both light and dark pages.

Copy feedback

The code frame's Copy button: icon-only and quiet at rest, tinted on hover, a visible ring on focus. After a copy the icon becomes a check for 1.6 seconds, the button turns success-green and a small Copied label slides in (announced politely). The tooltip title changes to Copied.
