  "or": [
    {
      "shinespark": {
        "frames": 143,
        "excessFrames": 6
      }
    },
    {
      "and": [
        "canHorizontalMidairShinespark",

Dev note: It's possible to save a couple frames by partially crossing the platforms before sparking, but getting a running jump is nearly as good.
