Wikipedia is very understandably taking measure against scraping bots as the age of the llm slop scraping is upon us. I should probably look at:

1. adhering to their terms
2. caching fetched images (I thought I was doing this, but we need to be part of the good guys here)
   
3. limiting runs against live urls (the previous point should hopefully help with this)
4. confirm whether I should mitigate against hammering other common sources, bgg is probably the next biggest source

Issue as discovered via build/lint:

Example:

This came up again as the monthly bump from dependabot creating a bunch of new PRs that all failed.

I have limited the lint ci action to run only against PRs, no longer on every push. This should help a little; still working out more.
