 * Deep Cuts — "the back of the sleeve".
 * The page reads like the reverse of an LP: a catalogue number, a numbered tracklist with dotted
 * leaders to the running times, and fine print at the foot (℗ year). Light mode is a cool card
 * stock, dark mode a matte black sleeve; the one accent is the label's ultramarine.
