Named rankings are on hold
The official game description confirms collectible keyboards and collection upgrades. Official art confirms visual variety. It does not currently publish a named keyboard list, rarity table, income multipliers, crate path, or comparable performance data.
That means color alone cannot become an item name, and an eye-catching screenshot cannot become a tier.
This first screen ranking readiness answer includes comparison criteria, official visual evidence, a measurement workflow, and no made-up tier rows.
