+// Fork 5 of 20 Parent id
+//
+// The leading 0s are important. In the above example, you only need 3 bits to
+// represent slot 5. However, you need 5 bits to represent all the forks at
+// the current level, so we must account for the empty bits at the end.
+//
+// For this same reason, slots are 1-indexed instead of 0-indexed. Otherwise,
+// the zeroth id at a level would be indistinguishable from its parent.
+//
+// If a node has only one child, and does not materialize an id (i.e. does not
+// contain a useId hook), then we don't need to allocate any space in the
+// sequence. It's treated as a transparent indirection. For example, these two
+// trees produce the same ids:
+//
+// <> <>
+// <Indirection> <A />
+// <A /> <B />
+// </Indirection> </>
+// <B />
+// </>
+//
+// However, we cannot skip any node that materializes an id. Otherwise, a parent
+// id that does not fork would be indistinguishable from its child id. For
+// example, this tree does not fork, but the parent and child must have
+// different ids.
+//
+// <Parent>
+// <Child />
+// </Parent>
+//
+// To handle this scenario, every time we materialize an id, we allocate a
+// new level with a single slot. You can think of this as a fork with only one
+// prong, or an array of children with length 1.
+//
+// It's possible for the size of the sequence to exceed 32 bits, the max
+// size for bitwise operations. When this happens, we make more room by
+// converting the right part of the id to a string and storing it in an overflow
+// variable. We use a base 32 string representation, because 32 is the largest
+// power of 2 that is supported by toString(). We want the base to be large so
+// that the resulting ids are compact, and we want the base to be a power of 2
+// because every log2(base) bits corresponds to a single character, i.e. every
