## Summary
- Remove unused `.top-head` / `.top-body` CSS rules that referenced missing GIF files (`top-head.gif`, `top-body.gif`), which caused `whitenoise.storage.MissingFileError` and crashed the prod container at collectstatic/startup.
- Drop a stray `{% load static %}` tag from `style.css` (not a Django template).
- Branch rebased onto current `master` (dockerize already merged via #21); this PR is the CSS-only fix.
## Test plan
- [ ] Merge and let deploy run (or redeploy scha prod).
- [ ] Confirm web container stays up (no WhiteNoise `MissingFileError`).
- [ ] Spot-check site CSS still looks fine on public pages.
- [ ] Separately: if Compose still warns about unset `$…` vars, escape `$` as `$$` in `~/Documents/secrets/scha/scha_prod.env` password/`DATABASE_URL`.
