• Unified keyboard definition with geometry and analyzer metadata
• Import support for Vial-style keyboard definitions
• Per-key alpha slot assignment so physical keyboards define their alpha cluster

• Built-in KLOR keyboard preset derived from the real Vial definition
• Layout comparison against weighted corpora
• Browser-local persistence for keyboards, layouts, corpora, and recent runs
