Diagnosed and fixed the Playwright element screenshot bug in the social-media-tools rendering pipeline — the browser_snapshot step was missing, causing full-page captures instead of cropping to the .card element.
- Root-caused full-page screenshot: browser_take_screenshot needs an element ref from browser_snapshot
- Added browser_snapshot step to rendering-pipeline.md — affects all 7 share skills
- Added browser_snapshot to the ToolSearch selector for deferred-tool environments
- Added CHANGELOG v2.5.1 entry documenting the fix
