1. Absolute Time Isolation: Uses Local Mean Time (LMT) by converting longitude directly to time offsets, making calculations 100% immune to device timezone bias.
2. The First Sunset Protocol: Observation strictly occurs on the first local sunset after the exact UTC Conjunction (Ijtima). If sunset precedes conjunction, observation is shifted to the next day.
3. Odeh Spatial Evaluation: Verifies if the pinned coordinate falls within the scientifically computed visibility polygons (Green, Yellow, Blue).
4. Danjon Limit Override: To prevent polygon boundary illusions, the moon must mathematically have an age of ≥ 8 hours and an altitude > 0° above the horizon to be deemed visible.
5. Istikmal Logic: If all conditions are met, the new lunar month begins the next day (29-day length). Otherwise, the current month completes a 30-day cycle.
