Greptile Summary

The PR adds Omapixel 1.0.0 as a locally maintained package for x86_64 and AArch64.

• Builds the CLI, Qt Quick Studio, and test suite from a checksum-pinned tagged source archive.
• Declares Qt, portal, image-format, MIME, icon-theme, and compression dependencies.
• Installs runtime configuration, translations, agent skills, desktop integration, documentation, and examples.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete blocking or independently actionable non-blocking issue identified.

The checksum-pinned recipe declares the dependencies needed by its build and runtime paths, runs native tests by default, and installs the expected executables and supporting assets.
