report.Should().MatchSnapshot();

Plain text is compared line by line. A mismatch shows unified hunks with three lines of context around each change:

Text did not match snapshot: tests/App.Tests/.snapshots/ReportTests/Renders.verified.txt

 </table>

Braces in the content are safe: the message is never used as a format string. Lines longer than 500 characters are cut, so one minified line cannot flood a log.

Line endings are always normalised, so a checkout with CRLF endings compares the same as one with LF.

For a short value there is MatchInlineSnapshot, which keeps the expected value in the test as a literal: see inline snapshots.
