Pull request overview
This PR refactors the UI panel headers to improve UX by introducing stacked header rows, adding quick-action icon buttons for copying/clearing sources, and updating preview rendering behavior to better handle toggling Shadow DOM.
Changes:
- Add “copy” and “clear” quick actions for Component and Styles editors, plus supporting clipboard/clear logic.
- Refactor header layout into stacked rows with new CSS utilities (including
.sr-onlyand icon button styling). - Update preview render targeting to recreate the preview host when switching from ShadowRoot to light DOM.
