Comment (by tlloancy):

 @afragen No rush — hope you're doing well at the hospital. Take care!

 Thanks for the gist! `tail_custom()` is clever with adaptive buffer.
 My version uses **char-by-char backward reading** — stops at first fatal,
 scales to any log size.

 **PR ready for merge.**

 Fixes #64155
 Props: @westonruter, @knutsp
