openai/gpt-5.2-chat → A (5:1)

Side A introduces a typed, deterministic BlockMasker with BlockKind tracking, adds a prose tokenizer that avoids linkifying inside code fences, enforces braced DSL item bodies with explicit parse errors, and rewrites HTML linkification to use the tokenizer—backed by extensive new tests. Side B mainly removes a wrapping section in vote_compare and tweaks CSS for ranking lists, which is largely presentational and far less architecturally significant.
