49// wrapping and budget-accounting can't drift apart (the *int signals
50// the mutation). The body renders inside the sandbox: its block
51// structure (headings, blockquotes, lists, columns, alerts) is
52// contained and cannot hijack realm chrome, so boards no longer needs
53// the write-time markdown blacklist. The opener survives the "> "
54// comment indentation at any depth (goldmark strips the "> " prefix
55// before the block parser runs).
