Released 2026-04

Confirms current value using the crates.io registry: the crate's first published version (0.19.0) was created 2026-04-08, the first point at which the software was independently obtainable. Note: GitHub carries an earlier v0.1.0 tag dated 2026-03-21, but versions before 0.19.0 were never published to crates.io/npm, so it's unclear whether the repo was public that early.
