In Karachi, the local standard for Asr follows the Hanafi juristic shadow (2x object length). Our node defaults to this standard to ensure alignment with local masjid congregations, while offering the standard (1x) toggle for international travelers.

For Karachi, we implement a 3-minute safety buffer between the final call for Sehri and the onset of Fajr. This ensures logistical certainty for those observing the fast in high-density urban environments.
