💎 Anti-Slop Design Philosophy

KeyCaster strictly adheres to production-grade, human-crafted frontend aesthetics:

• No Card Soup: Clean spatial rhythm using an authentic 8pt layout grid.
• High-Density Utility (Linear / Raycast): Subtle 1px borders (border-white/[0.08]), deep charcoal surfaces, and tactile micro-interactions.
• Typography Excellence: High-contrast pairing of Thmanyah Sans (for Arabic cues) and JetBrains Mono / Geist Mono (for English monospace typing).
• Accessible Contrast: Strict adherence to WCAG AA contrast ratios ($\ge 4.5:1$) with aria-live screen reader stage progress announcements.
