Fragment cost formula
F_final = CEIL(F_base * M_cost). M_cost is 1.00 for None, 1.50 for Standard Trait, 2.3333 for King's Fortune.
Cloning time formula
T_final = T_base * M_time * (1 - 0.05 * speed_level). The gamepass halves the final time.
Speed upgrade cap
Speed level is clamped between 0 and 10. The reduction multiplier is capped at 50% (level 10) to avoid negative durations.
