jeffkatz/TranstFeeds ? reverse-engineered prompt

Build me a simple web app for managing and browsing transit feed data.

I want a clean site where someone can load transit schedule data, view the main pieces like routes, stops, trips, and service details, and see it in a nice readable way. It should feel like a practical admin and viewer tool, not a flashy consumer app. Include a homepage, a few detail pages for the data, and basic navigation so it’s easy to move around.

If it makes sense, add forms for importing or updating feed data and make sure the app can handle common transit feed fields without breaking. Keep the design straightforward and responsive so it works on desktop and mobile. Use the existing project structure, and if you need current docs or examples for transit feed formats, look them up online first.
