First observed in KEYLIT at commit:27ad9016b4 on 2026-08-28, with origin confidence 1.00. That confidence is about the claim of where the capability started, not about the quality of the code.

Allele lineage

Each allele is a variant of the same capability. Select one for its own record, or compare two to see exactly where they diverge.

High-contrast, reduced-motion

CAALLELE:PIANO-RENDERER:3

Removes the glow animation and raises contrast to WCAG AAA.

Mutations on this gene

A gene here is a capability, not a file. “Piano Keyboard Renderer” is the thing that persists; the paths under Loci are where it currently lives and can change without the capability changing. Every figure on this page is read from the seeded KEYLIT fixtures.
