When the author handle is very long, the footer overflows past the Tangled logo on issue/PR OG images. The existing two thresholds (hide reactions at >20 chars, hide comments at >28 chars) were insufficient because even with only avatar + username + date visible, the layout could exceed the available 848px.
Add a third threshold (>40 chars) that also hides the date, and reduce username maxWidth from 480 to 440 for the 29-40 char range.
