harshitkamboj/Netflix-NFToken-Generator ? reverse-engineered prompt

Build me a simple Python script that takes a valid Netflix session cookie from an input.txt file and generates the Netflix nftoken login link in the console.

I want it to be a small local tool with no UI, just a script I can run from the terminal. If input.txt is missing, it should create it for me and then let me paste the cookie in. Please support a few common cookie formats, like a raw cookie string, Netscape style cookie text, and JSON. Then read the needed cookie values, send the request Netflix needs, and print the full https://www.netflix.com/?nftoken=... link.

Keep the code easy to read with comments that explain what each step is doing. If you need to look up any current request details online, go ahead. Also make sure it handles bad or expired cookies with a clear message instead of crashing.
