-- fixture: whole track wrapped in a `do` block with INDENTED dN (the
-- burn_this_book.tidal idiom that a column-0-only parser read as empty).
main = do
  let g = id
  d1 $ g $ s "jazz:2"
  d3 $ g $ s "drums_nes:3"      -- claimed-but-"missing" until the parser fix
  d4 $ g $ s "cpluck:1"
  d5
    $ s "meth_bass"
    # orbit 7                   -- `# orbit 7` ⇒ d8, not d5
-- d9 $ s "should_be_ignored"   (commented-out block must not parse)
