   Synthology Shared DICOM Viewer — widget styling
   ═══════════════════════════════════════════════════════════════════════════
   Scopes everything under .synth-dicom-viewer so host pages can drop the
   widget anywhere without their own CSS bleeding in (or leaking out to the
   shared SynthShell chrome). Colors lean on --brand from SynthShell so the
   viewer inherits each product's theme (plum for EE, teal for SRE, etc.). */
