## What is ChromaHunt Pro X?

ChromaHunt Pro — Precision Color Delta Training

Designed for players who demand measurable challenge. Each level reduces the hue delta between the target block and surrounding grid. At Insane difficulty, level 30+, the delta reaches 0.025 — imperceptible to the untrained eye.

TECHNICAL SPECS
• Grid sizes: 3×3 (Easy) to 6×6 (Insane)
• Delta range: 0.025 (minimum) to 0.3+ (beginner)
• Timer: 15–30 seconds (difficulty-scaled)
• Correct tap: +1.2s reward | Wrong tap: -3s penalty
• Colorblind Assist: 1.8x delta amplification

ZERO DEPENDENCIES
• No URLSession calls — 100% offline
• No NS*UsageDescription — zero permissions
• No third-party SDK — pure Swift + SwiftUI
• UserDefaults only — instant load, no migration

PERFORMANCE
• SwiftUI-native rendering at 60fps
• Acid Graphics visual language: high-saturation palette, fluid metal aesthetic
• Particle burst on correct answer, red-border flash on error

PRIVACY
Data never leaves the device. No analytics, no crash reporting, no ads.

A pure skill test. No luck. No random. Just your eyes versus the delta.
