Problem:
copyright.html, embed.html and index.html contain a hardcoded <title>Wikidata Query Service</title> element, which is not suitable for all installations. It should be configurable.
Acceptance criteria:
- the name of the query service can be adapted for a project in one single place
Approach
- Have a JS script that runs on page load for all of the pages referenced that replaces the titles with other configured titles
