/**
 * Policy Preview Modal — file preview for artifact-backed policies.
 * Used by both the modal (PolicyPreviewModal.open via ModalOverlay) and
 * the inline mount on the policy detail Content tab.
 *
 * The modal layout reuses ModalOverlay's canonical structure:
 *   .modal-overlay.policy-preview-overlay > .modal-content >
 *     .modal-header (title + close)
 *     .modal-body   (iframe / card)
 *     .modal-footer (Download button — only when present)
 *
 * We override the modal-body height/padding so the iframe can fill it.
