Party scale

Sweet spot is 5. Edges pay extra HP fat and extra foe damage.

share = n / 5
edge  = ((n − 5) / 5)^2
hpMult  = share × (1 + 0.2 × edge)
dmgMult = 1 + 0.45 × edge

Edges (2–4 and 6–10) pay extra HP fat and extra foe damage. Scale freezes at combat start.

Frozen at each combat start from party size in the pull. Authored HP/ATK are the 5-player baseline.
