ChoiJi92/carrot_market_clone — reverse-engineered prompt

Build me a Carrot Market style second hand marketplace web app in Korean. I want it to feel like the real Daangn homepage, with a main landing page, header and footer on every page, popular used item listings, and buttons that can take users to the item list.

Users should be able to sign up and log in through floating modal windows. After logging in, show their nickname and a basic profile image in the header. Let logged in users write posts with title, content, multiple image uploads, image previews, and location access. If someone isn’t logged in and tries to write, show a friendly login required message.

The item list should show posts newest first, support search, likes, comment counts, and infinite scrolling. Each item should open a detail page with an image slider, likes, comments, and edit or delete buttons only for the original writer. Comments should also be editable or deletable only by their author.

Use React style frontend patterns and mock or connect API calls as needed. Look up current docs online if needed.
