Release notes for 5.19.1.

Released: 2026-09-08

Updated the zfb peer and development dependency family to 2.16.0 (47c149385). The upstream release carries one bug fix: zfb's esbuild version-gate spawn (ensure_binary_verified) now retries on ETXTBSY through zfb-build's existing retry loop instead of a bare .output(), so a build no longer dies with Text file busy (os error 26) on the first exec of a binary a packaged zfb has only just written to a tempdir. @takazudo/zfb-md-wasm changes only its README — every shipped artifact keeps its 2.15.1 byte size — and no public API, export, config default, or engine requirement moves.
Raised the @takazudo/zdtp peer floor to ^0.5.2 (47c149385). The upstream release is additive for this consumer: a stable data-zdtp-action attribute on the header actions, and a fix keying popover and header items by that action id instead of by display label. There is no storage-key or config-shape migration, and the vendored design-token-panel constants mirror stays conformant against the real @takazudo/zdtp/constants leaf.
