FireboIt/trial_room — reverse-engineered prompt

Build me a Chrome extension called Trial Room that lets someone virtually try on clothes while shopping online. The user should be able to upload their own photo in the extension popup, open a clothing product page on Amazon US, Amazon India, or Coupang, then click a Try It On button and have the main product image replaced with an AI generated image showing the garment on them.

Keep it desktop focused and lightweight. The user photo should stay in the browser, and any API keys must stay hidden on a small Flask backend proxy using environment variables. The backend should call the KlingAI or Kolors virtual try on service, handle CORS, and return the generated image to the extension.

Please include clear setup steps for loading the unpacked Chrome extension, running the Flask proxy locally, and optionally pointing it at a hosted backend. Add basic privacy policy wording that says photos are not stored or shared. Look up current docs online if you need to.
