 * Service deciding whether a node can be previewed in the browser.

 * Some file types are rendered natively (images, videos, PDF). Every other
 * type relies on a server-side "pdf" rendition produced by Alfresco's
 * transform service. Asking Alfresco to create that rendition for a type it
 * cannot transform (archives, binaries, ...) generates noise in the logs and
 * dead-end viewers.
 *
 * `listRenditions` (GET /nodes/{id}/renditions) returns only the renditions
 * applicable to the node's source mimetype and does NOT trigger any transform,
 * so it is a cheap, side-effect-free way to know up-front whether a "pdf"
 * rendition is available. Results are cached per mimetype for the session and
 * are reusable across apps (espaces, marches, media, ...).
