  प्रकाशिका" - an author phrase welded to a generic label. That is not a
  citable title, and it is what the client saw as "Vadirajathirtha
  virachitha". The Grantha library holds the real title and author, so
  the page carries only the library's stable id (data-grantha-id) and we
  resolve the rest here, at read time. Correct a name in the library and
  every citation on the site is correct on the next load - nothing to
  rebuild, nothing to re-upload.
  Reads only, and the library's GET endpoints are public: no API key is
  sent from the browser, and none may ever be put in this file, which
  any reader can fetch. */
