Notice and attribution

• NOTICE carries the project copyright line and the ANTLR attribution, as Apache-2.0 expects for redistributed derivatives.
• Site fonts and build tooling (VitePress, Vue, Shiki, MiniSearch, Inter) keep their own MIT / OFL-1.1 licenses; see THIRD_PARTY_NOTICES.md.

Icon provenance

The icon at the repository root was supplied by the project owner and is used for the README, site logo, favicons and social preview image. Its origin and the possible third-party reference in the artwork (a cat silhouette resembling GitHub's Octocat mark) are still the owner's to confirm; the artwork is not claimed to be original or unrestricted. See THIRD_PARTY_NOTICES.md.

Contributing and redistribution

By contributing, you agree that your contribution is licensed under Apache-2.0. Redistributions must keep the LICENSE, NOTICE and THIRD_PARTY_NOTICES.md files, and modified files must carry prominent notices stating that they were changed.
