How it works — Reverse Alpha Blending
Gemini composites its logo onto your image using standard alpha blending.
By using the exact captured watermark alpha maps from the official open-source repo,
we can perfectly invert this operation with zero quality loss.
original = (watermarked − α × 255) / (1 − α)
