iharnoor/BudgetSF ? reverse-engineered prompt

Build me a map first web app for San Francisco that helps people find budget friendly spots around the city. I want it to feel like a survival guide, not a review site, with a big interactive map, searchable pins, and a near me view so people can quickly find the closest cheap eats, groceries, gyms, work spots, free things, and other useful places.

It should also include a few simple guide pages like a budget meal plan, free things to do, getting around, trip planning, and community events. Let people sign in and submit new spots, then have a community voting system so only the best suggestions make it onto the map. Add semantic search so users can search in a natural way, like asking for cheap lunch, free coworking, or a good place to study. Make it modern, clean, and easy to browse on mobile. If you need to check current docs for anything, go ahead and look them up online.
