Giveaway — Rafflecopter Proof of Fairness

On October 5, 2026 at 4:58 PM, Rafflecopter ran the giveaway “Giveaway” on Instagram. The winner was @abymontalvo, selected from 31 unique participants using a cryptographically secure random number generator (CSPRNG) with SHA-256 hashing.

SHA-256 hash: 5600fe1fc826fdca01c6c70f5abf62b470a89442c2d556abf71213a18700e1b7
