Brownout — third-party notices

Brownout, Copyright (c) 2026 de:volt, MIT licensed (see LICENSE). The engine
was extracted from the de:volt application's `@devolt/simcore` package; the
copyright holder is unchanged by the extraction.

This file records the third-party material Brownout redistributes. Sections 1
through 3 cover the published npm package; section 4 covers a binary that
exists in the repository but is NOT published (the `files` allowlist in
package.json ships only `dist`, `docs`, `LICENSE`, `README.md`, and this
file).

4. MicroPython firmware — repository test fixture, NOT in the published
   package
   File: test/fixtures/firmware/pico-micropython.uf2

   Copyright (c) 2013-2026 Damien P. George and contributors.
   License: MIT

   MicroPython v1.28.0 (2026-04-06), board target RPI_PICO, mirrored from
   https://micropython.org/resources/firmware/RPI_PICO-20260406-v1.28.0.uf2
   SHA-256: 00aedb8431ebea83b470ef909509f16432c5b1b43e8f6eaf015f6f9560bc8152

   Bundled so the Pico integration suites run without an app checkout. The
   package tarball excludes `test/`, so this binary is not redistributed on
   npm — a consumer supplies its own firmware through setMcuFirmware().

   The RPI_PICO port additionally contains pico-sdk components under
   BSD-3-Clause. Consult the upstream v1.28.0 licence tree before
   redistributing this binary or updating it; the provenance record in
   test/fixtures/firmware/README.md must be updated with it.
