Photo-feed social app — viral twin

The prompt

Build a single-file photo-sharing feed artifact: a grid of square photo posts, each with a like button and a caption, plus a simple upload form that adds a new post to the top of the grid. Self-contained, no backend.

Expected result

A working photo-feed artifact — scrollable grid of posts, working like counters, and new uploads appearing instantly at the top.

Why it works

Naming the exact interaction set (grid, like, caption, upload-to-top) keeps the model from wandering into unrelated social features like DMs or stories.
