  * Quest 3 thumbstick locomotion (rig-relative).

- * Mapeamento:
- *   • Joystick para frente (axes[1] < -0.7) e soltar (volta a 0)
- *       → teletransporta para o ponto apontado pelo controle direito
- *         (raycast contra `scene.children`). Sem alvo → passo de 0.5 m
- *         na direção do controle.
- *   • Joystick para trás  (axes[1] > 0.7) → passo de 0.3 m para trás
- *         (em relação à orientação do XROrigin / yaw da câmera).
- *   • Joystick lateral   (|axes[0]| > 0.7) → snap-rotate ±30° em torno
- *         do eixo Y do XROrigin.
+ * Mapeamento (thumbstick = axes[2]/axes[3] em xr-standard):
+ *   • Para frente (axes[1] < -0.7), libera (axis volta a ~0) → teletransporta
+ *     para o ponto onde o usuário está olhando (raycast da câmera). Se não
+ *     houver geometria atingida, dá um passo de 0.5 m na direção do olhar.
+ *   • Para trás  (axes[1] > 0.7) → passo de 0.3 m oposto ao olhar.
+ *   • Lateral   (|axes[0]| > 0.7) → snap-rotate ±30° no eixo Y do rig.
  *
- * Lê apenas o thumbstick (axes[2]/axes[3] em xr-standard) — não toca em
- * grip nem trigger.
+ * NÃO lê grip ou trigger — esses são responsabilidade exclusiva de
+ * XRGrabbable e XRControllerMeasure, respectivamente.
