滚动截图（Scrolling Screenshot）

Scrolling Screenshot (Edge) v1.0.0
Select an area on a webpage, capture it while scrolling, stitch the shots automatically, and add quick annotations before saving. Built on Manifest V3; all capture and stitching happen locally—nothing is uploaded.
Key features
Three capture modes
Area capture: draw a box inside the viewport, scroll manually, and the extension slices & stitches on the fly.
Full-page capture: auto-detect the scrollable root and shoot from top to bottom in one pass.
Container capture: pick any scrollable element (including same-origin iframes) and capture it end-to-end.
Auto-detect scrollable containers: works for document.scrollingElement, regular overflow elements, and scrollers inside same-origin iframes.
Overlap estimation & seamless stitching: uses pixel-wise mean-square error to find the overlap between adjacent frames, minimizing seams and duplicates.
In-page preview: after capture, an overlay opens on the current tab—review and save the final image locally.
