Migrate PDF documents to Cloudinary #52
Description
Warning
In October 2025, Firebase Storage will require a paid subscription to continue hosting the site's PDF documents.
Firebase Projects, including this site running under the no-cost Spark Plan, will have inaccessible file uploads, downloads, and hosting via the Firebase Storage.
For more information, see https://firebase.google.cn/docs/storage/faqs-storage-changes-announced-sept-2024
Task
Migrate the site's static PDF documents to a standard (free-tier) Cloudinary account, since this site's Firebase project has no plans to subscribe to the Firebase Blaze plan in the long run.
