Reviewer's Guide

The PR adds a Vercel-style floating developer toolbar by moving the UI to a bottom-right dark control bar, refining its visual states and popup positioning, and updating iframe pointer-event handling so toolbar interactions work without blocking the underlying page.

File-Level Changes

Change	Details	Files
Reworked iframe hit-testing so the full-page overlay can receive events while only the toolbar controls intercept page interaction.	Use a dedicated iframe ID for duplicate-injection checks. Enable iframe pointer events and disable them on the iframe document outside the toolbar. Explicitly re-enable pointer events for the toolbar element.	extension/content-script.js
Redesigned the toolbar layout and visual styling around a Vercel-inspired dark floating control bar.	Move the toolbar to the bottom-right and refine spacing, sizing, borders, shadows, and icon treatment. Update hover, active, status-indicator, tooltip, and menu colors and states. Reposition tooltips and menu panels above the toolbar for the new orientation. Make hidden menu panels non-interactive until opened and enable interaction when open.	extension/toolbar.html
