Every sig anchor × rank at A2. Sig levels in between interpolate smoothly (PCHIP) and round to the nearest 10 BHR — matching the in-game display.

BHR at each signature level by rank, at maximum ascension (A2). The curve is concave — sig 0 → 100 captures roughly two-thirds of the gain from sig 0 → 200.
