def parse_value_at_start
  # Wrap in a minimal DMS document and parse, then extract the value.
  # Since we need to parse a raw value (not a key-value pair),
  # we wrap it as `_v: <value>` and parse the front matter.
  # Actually simpler: parse as a scalar root document.

  # Build: the value might be followed by sigil chars, newlines, etc.
  # We'll use a fresh Parser at lite mode.
