CareerAtlas/career_atlas ? reverse-engineered prompt

Build me a web app called CareerAtlas that helps people find jobs on a map.

I want users to be able to search for jobs with a few filters, see the results plotted on Google Maps, and click a job to get more details. The app should also show useful neighborhood info like Walk Score, and pull in company or job info from Indeed and Glassdoor when available. Let users save jobs they like so they can come back to them later.

Make it feel like a clean job search tool with a map first experience, not just a plain list of listings. Use a modern front end and a Rails backend, and wire up the API keys through environment variables so I can plug in my own accounts. If you need to check current docs for the APIs or libraries, go ahead and look them up online. Also include a simple way to run the app locally and make sure the main search and saved jobs flow works end to end.
