gnovotny/nothing-to-watch — reverse-engineered prompt

Build me an experimental movie discovery site where people can explore a huge wall of film posters, ideally tens of thousands, as an interactive visual map instead of a normal grid. I want the posters arranged in a force based Voronoi style layout so nearby movies feel related, and it should feel smooth and fast in the browser even with a very large dataset.

Please make it work well on desktop, tablet, and mobile, with pinch or scroll zoom, pan, hover or tap selection, and a nice flow between an intro screen, a browsing or selection view, and a preview view for a chosen film. Load movie info from local JSON files and poster images from media folders, with support for different image sizes so performance stays good.

Give it a polished responsive UI with accessible controls, simple settings, and optional light and dark themes. Include sensible defaults for local env setup, plus basic tests and a production build. If anything is unclear, look up current docs online and make practical choices.
