What it costs vs what you'd save

The starter prompt

Build a Chrome extension that lets me click on any webpage element to apply a CSS blur filter for screen sharing. Include a rectangular area selection tool, custom blur intensity sliders, and a 'Keep Blur' toggle that saves selectors to chrome.storage.local to persist blurs on specific URLs. Add an option to mask the current tab's title and favicon.
