      # GroupDocs.Viewer's page-rendering paths (PDF, presentations, image-
      # bearing documents) call System.Drawing internally on .NET — Linux
      # runners need:
      # - libgdiplus           : managed System.Drawing implementation
      # - libfontconfig1       : font discovery
      # - ttf-mscorefonts-installer : Arial / Times New Roman / etc. The
      #   `render_page` tool rasterizes pages to PNG and lays out text glyphs;
      #   without MS core fonts the engine fails on font resolution and the
      #   wrapped error reads "An error occurred invoking 'render_page'."
      #   Pattern lifted from the sibling python-conversion Dockerfile. EULA
      #   accepted via debconf-set-selections; fc-cache refresh post-install.
      # Note: the .NET Docker base aspnet:10.0 inherits these fonts from
      # Debian-bookworm-slim; bare ubuntu-24.04 runners do not.

      # prefix or /usr/local/lib (a failing run showed its dlopen only probes the
      # package dir, the .NET shared-framework dir, and /usr/lib). So install via
