/*
  YouTube Music playlist export. Loaded only by /ytm/ via the layout's
  `stylesheet` front matter hook, like blackjack.css, so none of this reaches
  any other page.

  The page uses the plain .wrapper rather than .wrapper-post, so the form and
  the JSON panes span the same width as the footer. Only the prose (the lede
  and the key steps) is held to the reading measure.

  Buttons follow /blackjack/: bracketed amber text, because amber means
  interactive everywhere on this site. No new colors: errors borrow the
  palette's existing red (--syn-var), as .notfound-err and the blackjack table
  already do.
