The CI image's rustfmt reformats these files (multi-line assert!/tracing! macros, match-arm and struct-variant wrapping) — pre-existing drift that the Format job caught. Reformat to match. Pure formatting; no logic change. main.rs also gets a blank line before a standalone comment so rustfmt stops mis-indenting it as a trailing-comment continuation.
