Chrome Extension Data Scraper

I need a small Chrome extension that can grab specific text content from pages I’ll identify and, at the click of a toolbar button, package that data into a downloadable CSV file. All processing should happen locally inside the browser—no server calls—so please rely on standard Chrome APIs (Manifest V3), plain JavaScript or TypeScript, and familiar libraries only when truly helpful.

Here’s the flow I’m after:
1. I visit one of the target pages.
2. I click the extension’s icon.
3. The extension reads the text elements I previously defined (I’ll give you precise selectors in chat), structures them into rows and columns, and immediately triggers a CSV download.

Deliverables
• Full, well-commented source code and manifest files
• A short README covering setup, usage, and field mapping
• Quick demo (screenshots or video) proving the CSV matches the on-screen text

Acceptance
The extension must run smoothly in the current Chrome release, respect the selectors I supply, and generate a clean, comma-separated file every time without needing extra configuration. Once you hand over the code, I’ll test it on a handful of live pages; if the CSV mirrors the displayed text, the job’s done.
