--   * PokecenterNurseScript's `special HealMachineAnim` used to be a bare
--     (wrong) sfx: the balls, the flashing and MUSIC_HEAL all have to appear,
--     ON the machine at the counter's left end, and the nurse's next line
--     must wait for the last flash
--   * a mart clerk's shelf came from data/generated/marts.lua being absent,
--     so every shop opened empty: Cherrygrove must stock its four items with
--     ItemAttributes prices and a purchase must move money and the PACK
