Blank lines between a block scalar header and its first content line come before the indent token, so the earlier blank-line capture skipped them. Buffer leading blanks while the block indentation is still pending and flush them as empty content once the indent is established, in the shared indentation path used by both scan loops. Also fix folded bodies to emit a break for a leading blank rather than folding it into a leading space. This closes the last block-scalar blank-line edge from #57.
