UNDERGROUND FX MASTER REBUILD (fresh-shell pass)

What this zip is:
- A fresh master-shell rebuild using the previous site as a CONTENT/FUNCTION source rather than as the design foundation.

What was rebuilt:
- public header/nav/footer shell
- homepage hero and premium sections
- DJ wall page
- schedule page
- news page
- events page
- requests page
- about page
- admin shell + admin dashboard
- now playing fallback logic
- stream config updated to radio.undergroundfxradio.com:9000/stream

Important:
- This is the fresh-shell/master architecture pass.
- Existing feature pages and data files are still present so the working feature stack remains available.
- DJ data was preserved from data/djs.json.
- Temporary admin password currently in data/settings.json and stream_lib.php defaults:
  admin / TxHL7RqdSjQbSB

Next ideal passes:
- exact page-by-page conversion of every remaining secondary page into the new shell
- exact live-source DJ roster audit
- final production hardening / install cleanup
