developerrahulofficial/love-score-calculator ? reverse-engineered prompt

Build me a cute Love Score calculator web app that lets me paste in a chat and get a score from 0 to 100 for the romantic potential of the conversation.

It should feel playful and polished, with a simple input area for chat text, a button to calculate, and a results section that shows the final percentage plus a clear breakdown of why the score came out that way. Please use the rules from the README, like reply speed, emoji usage, message balance, and consistency, and start from a base score of 50. Show the score in a fun way, like a progress ring or bar, and make the result easy to understand at a glance.

If it helps, include a couple of example chats so I can try it quickly. Make the page responsive, attractive, and easy to use, and if you need current docs for anything, look them up online.
