+<!--
+  Hardened ImageMagick policy for Pimcore.
+
+  Pimcore rasterises uploaded, untrusted SVG assets through ImageMagick (via the
+  Imagick PHP extension). ImageMagick's SVG renderer follows <image xlink:href="...">
+  references to other "coders" / pseudo-protocols. 
+  
+  This policy denies the coders those hrefs invoke. SVG itself stays enabled, so
+  legitimate SVG thumbnails still render, but any href that points at a file-reading,
+  text-rendering, scripting, or network coder is refused with "not authorized".
+
+  NOTE (scope): This is an ImageMagick-level control. It cannot inspect SVG XML and
+  therefore does NOT literally strip <script> tags or href attributes. Removing
+  <script>/href from SVG (the stored-XSS concern, and defence-in-depth for the above)
+  is an application-layer job for an SVG sanitiser in pimcore/pimcore, not this image.
+
+  Coders deliberately LEFT ENABLED so Pimcore previews keep working:
+    * SVG / MSVG / MVG - SVG thumbnail rasterisation (internal renderer needs MVG)
+    * PDF / PS / EPS / XPS - document thumbnails via the Ghostscript delegate
+    * image/video coders - normal asset processing
