🎨 Palette: Replace anchor tag with button for JS action in Visualizer

[sheepdestroyer]

💡 What: Replaced the <a href="#"> tag used for clearing annotations with a <button type="button">. Button styles were reset to match the original inline visual style.
🎯 Why: Using <a href="#"> for JavaScript actions forces a page jump to the top of the window when clicked. Using a semantic button fixes this disruptive interaction while preserving visual appearance.
📸 Before/After: Visual appearance remains exactly the same, but the scroll jump on click is removed.
♿ Accessibility: Replaces an invalid semantic link (one without a real navigation destination) with a semantically appropriate button element for a user interface action.

Reviewer's Guide

The PR fixes the annotation-clear interaction in the Visualizer by replacing a placeholder anchor with a semantically appropriate button, retaining the existing JavaScript handler and visual styling while eliminating the page jump caused by href="#"; the rationale is also recorded in the project palette.
