dev.knotless.getBlame

Who last changed each line of a text file at a revision, as git blame finds it: the file's text, the ranges its highlighting paints, its lines in runs from the same commit, and each of those commits once. A binary file, or one over 256 KiB, is refused. No authentication needed; asked as an account, with a service token or the pages' session cookie, a private repository it is a member of is read too, and the answer is that account's alone.
