 *
 * Set iniziale: famiglia Creative Commons 4.0 + Public Domain Mark + i tre
 * rights statement più comuni (InC, InC-EDU, CNE). Gli altri statement di
 * RightsStatements.org (InC-NC, NoC-NC, NKC, UND, ...) si aggiungono al
 * bisogno dal pannello admin.
 *
 * `file` è il nome del testo legale in storage/app/public/licenses/ (incluso
 * nello zip di download dei media e servito al frontend via storage:link);
 * NULL per mark e rights statement, che non hanno un testo legale. I testi CC
