  //   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
  // log2(32) = 5 bits. That means we can lop bits off the end 5 at a time without
