207 source block shallower than branch

// PINS: a Source block opened on a nested continuation may have body
// text SHALLLOWER than that continuation (`| cfg` at 8 spaces, the
// block at 4). The gatherer stopped on any shallower line without `}`,
// so the block never closed (PARSE001). Sibling continuations (`|` / `!`)
// still stop the gatherer; 210_139 pins the mid-line close. Ward's GET /
// dashboard is this shape: parse-ini's `| cfg` then fmt.blk HTML.
