OptiTronOffical/OptiStore ? reverse-engineered prompt

Build me a simple browser based app for browsing PS4 and PS5 package libraries.

I want one page for PS4 and one page for PS5, both working as plain static HTML pages that I can open locally or host on a simple web server. The PS4 page should let me search by title or title ID, filter by region and kind, sort the list, and open a detail view that shows all package links, sizes, versions, minimum firmware, and whether they are base games, updates, DLC, themes, or avatars. The PS5 page should load separate catalog files, let me switch between them with tabs, filter by category and region, and show any useful download or password help if a link is locked.

If a catalog file is missing, the page should still load and offer a way to choose a JSON file from disk. Make it clean, fast, and easy to use on a normal browser, including on a PS4 browser over the local network. If you need to look up current browser support details, feel free to check online.
