Reproduce four authored-code delimiter failures, protect actual code/pre regions, and apply enabled formatting only to raw visible text after original source positions are captured. Preserve attributes, comments, entities and the reference metadata/subscript boundary. Keep original MIT attribution and extend real browser acceptance.
Validation: 642 core tests and 100% measured line coverage, zero-warning Release build, full formatting. Previous c3c735e CI is terminal with native/published106 and installed105 per channel, zero skips. New hosted acceptance remains required.
