// line until a blank line terminates it, and markdown inline rules (bold,
// italics, links) don't apply inside the block. Without surrounding blank
// lines, the line right after our placeholder div gets absorbed as HTML and
// its markdown is not parsed. We consume any adjacent newlines in the match
// and emit exactly `\n\n<div></div>\n\n` so the HTML block starts and ends on

// Consume ALL adjacent newlines (\n*, not \n?) so the emitted `\n\n…\n\n`

// on save; a `\n?` regex on reload would only consume one of those two
// newlines, so every cycle would add a net newline on each side of every
// marker — causing tracks running on an open note to steadily inflate the
// file with blank lines around target regions.
