If only THIS page should have the full-page background
Tell me the page URL/slug (it’s “formulare-si-conditii-de-inscriere-2026” from your screenshot), and I’ll scope the background rules to that page only (WordPress adds a body class like page-id-XXXX or page-slug-...).
If you want, paste the page’s body classes (view source → search body class="...") and I’ll give you the exact scoped selectors.
