 * DOM hierarchy emitted by the assembler:
 *   <g class="character">       <- bob (transform: translate)
 *     <g class="lean">          <- static forward rotation, pivot near leg tips
 *       arm-L, arm-R,
 *       part-shadows,
 *       leg-L, leg-R,
 *       body, eyes, mouth
 *
 * The two legs use the same side-view gait and are offset by half a cycle.
 * They are not mirrored: this character faces right, so both knees bend
 * forward in the walk direction.
