+/**
+ * This splits a string on a top-level character.
+ *
+ * Regex doesn't support recursion (at least not the JS-flavored version).
+ * So we have to use a tiny state machine to keep track of paren placement.
+ *
+ * Expected behavior using commas:
+ * var(--a, 0 0 1px rgb(0, 0, 0)), 0 0 1px rgb(0, 0, 0)
+ *       ─┬─             ┬  ┬    ┬
+ *        x              x  x    ╰──────── Split because top-level
+ *        ╰──────────────┴──┴───────────── Ignored b/c inside >= 1 levels of parens
+ *
+ * @param {string} input
+ * @param {string} separator
