This updates HTML validation to auto-correct expected text content while only failing mismatches below a similarity threshold. It keeps security checks intact by validating descendants before text replacement, preventing nested unsafe tags/attributes from bypassing validation. It also skips text substitution for image IDs/tags to avoid malformed output if expected-text maps are misconfigured. Tests were expanded to cover tolerant matching, edit-distance helpers, nested unsafe-content regressions, and the image-ID substitution guard.
