cncf/gitjobs ? reverse-engineered prompt

Build me a simple open source job board for developers called GitJobs.

It should let people browse open source job opportunities and filter them by things like language, technology, and foundation. I want the site to make it easy to find roles that contribute back to open source projects and highlight those opportunities clearly. The main experience should feel clean and developer friendly, with a search and filter area, job listings, and a job details page.

Please also include a way to generate embed code from the current filters so other websites can show matching jobs in an iframe. It should work for both full filter views and single job sharing. For a single job, generate a nice shareable card and code in a few formats like HTML, Markdown, and AsciiDoc.

If you need to look up current docs online for anything, feel free to do that. Keep it polished but simple, since this is still an early beta project.
