Parameters:
| Parameter | Description |
|---|---|
| P | Pressure, [Pa]. |
| zi | Mole fractions (N×1 range, must sum to 1.0). |

Bubble & Dew Point
Calculates bubble point and dew point (pressure and temperature) for a ternary hydrocarbon mixture using Peng-Robinson EoS. - **Bubble point**: first vapor bubble forms from liquid (V = 0) - **Dew point**: first liquid droplet forms from vapor (V = 1) Uses the property-array workflow: build property table, then pass `zi` and `props` to saturation functions.
