Function isOutOfSign

isOutOfSign(
    transitLongitude: number,
    natalLongitude: number,
    aspectAngle: number,
): boolean
Check if an aspect is out-of-sign (dissociate).
Parameters
- transitLongitude: number
  Transiting body longitude
- natalLongitude: number
  Natal point longitude
- aspectAngle: number
  The aspect angle
Returns boolean
True if the aspect crosses sign boundaries unexpectedly

Remarks
An out-of-sign aspect occurs when two bodies are within orb of an aspect but their signs don't match the expected relationship. Example: Sun at 29° Aries, Saturn at 1° Capricorn = 88° (within square orb) but Aries-Capricorn is not a square relationship (should be Aries-Cancer).
