LinkedIn Comments Export Script

I need a clean-coded Python script that accepts a single LinkedIn post URL, signs in with supplied credentials, and exports every comment from that post to a neatly structured JSON file. Alongside each comment, the file must also hold:

• the total likes/reactions count for the post
• the commenter’s public name, headline and profile URL (user details)

The JSON keys and overall schema are up to you as long as they remain consistent and human-readable.

Key points you must meet
• Headless, “human-like” browsing—no rate-limit flags or CAPTCHA loops.
• No official LinkedIn API keys; the routine has to rely on browser automation or similar stealth techniques (Selenium + undetected-chromedriver, Playwright, etc.).
• Works on any recent Python 3.x version and common OSs (Windows, macOS, Linux).
• A simple README covering environment setup, credential handling, and a one-line run command.

I will decide quickly, so please attach past work that proves you have solved comparable scraping or LinkedIn automation challenges.
