Release notes for 5.19.0.

Released: 2026-09-07

Bug Fixes

• The gen-z-index and gen-component-tokens bins report a descriptive error instead of a raw Node stack trace. A missing input file now names the path and says which file it is, while EACCES / EISDIR keep their own message rather than collapsing into a misleading "not found", and a top-level handler prints the message to stderr and exits 1 for any deliberate throw. A non-Error throw prints its string form rather than a bare undefined. (83a4c6f7a, 134248eba)
