/**
 * Splits markdown into blocks that Prism's markdown grammar highlights the same way
 * on their own as it does in the full document, so unchanged blocks can be cached.
 * Joining the returned blocks always yields the original string.
 *
 * A block ends where a run of blank lines starts, so each block keeps its leading blank
 * lines (indented code needs them). No split happens inside a ``` fence, front matter or
 * multiline markup or link references, or right before a `---` line, which Prism
 * would read as front matter. Whitespace-only lines stay in their block because
 * Prism's inline emphasis can span them.
 * Fences follow Prism's rule, not CommonMark's, so the split matches what Prism sees.
