+Enable `mod_rewrite` and `mod_headers`, and deploy the current `public/.htaccess` from the Shopware template.
+The following additions restrict existing HTML files under `media/` and `thumbnail/`, and apply the same policy to SVG files.
+Place the rewrite condition and rule before the existing rule that serves files directly; keep the header directives in the `mod_headers` block.
+
+```apache
+<IfModule mod_rewrite.c>
+    RewriteEngine On
+    RewriteCond %{REQUEST_FILENAME} -f
+    RewriteRule ^(?:media|thumbnail)/.*\.(?i:html)$ - [E=SHOPWARE_STATIC_HTML:1]
+</IfModule>
+
+<IfModule mod_headers.c>
+    Header set Content-Security-Policy "script-src 'none'; object-src 'none'; frame-src 'none'; base-uri 'none'; form-action 'none'" env=SHOPWARE_STATIC_HTML

+        Header set Content-Security-Policy "script-src 'none'; object-src 'none'; frame-src 'none'; base-uri 'none'; form-action 'none'"
+    </FilesMatch>
+</IfModule>
+```
+
+These rules leave application-rendered HTML and bundled HTML applications unchanged.
+Custom static documents must work without scripts, embedded documents, base URL overrides or form submissions; images and styles remain permitted.

+Missing HTML media files return 404; application-rendered HTML and bundled HTML applications retain their own response policies.
