* Tests remove the temp files they write Every test run left about 22 folders and files in the system temp directory: xref, alias, template, insert, linetype, script and recent-file fixtures, plus the pathless screenshot folder. The PDFBOOK test also wrote its second book to `$TMPDIR/b.pdf`, because `a^b.pdf` splits into `<prefix>-a.pdf` and `b.pdf`, and then removed a file that was never written. Tests that write files now use a `TempDir` guard (`tests/support/temp_dir.rs`, shared by the engine's unit and integration tests and copied for the UI crate). It gives each test its own folder and removes it on drop, even when an assertion fails. The PDFBOOK test also checks that both books land in its folder. The five tests that write pathless screenshots hold a test-only lock, so the shared screenshot folder can be removed once empty without racing another test's write.

A failed PNG write or flush removes the partial file, since the reply carries no path for anyone else to clean up.
