fallback to fetching content from browser if server-side fetch fails

Feature idea: if the usual server-side article fetch fails, fall back to fetching content from the browser. In other words: gracefully degrade content fetching so it automatically / intuitively works in more situations.

This relies on the API telling us when a server-side fetch fails. Is that supported?

Are there also "soft" failures to worry about (like, where the server-side fetch appeared to work but fetched no content or broken content)?

Ideally configurable per domain name / base URL (similar to the existing "content fetching from the browser" option in preferences).

Another idea would be to have a hotkey or other user-controlled UI/UX to fetch content from the browser so it can be done manually. I usually click through to double-check added content anyway.
