Natron

Domain knowledge for working on the Natron compositor's own C++ source code (Engine/Gui/HostSupport). Use when navigating, fixing, or extending the Natron codebase, doing Qt5/Qt6 work, building Natron, building its Sphinx docs, or triaging its GitHub issues.

Upgrade the local Natron MacPorts portfile overlay against upstream MacPorts, and build Natron into a macOS arm64 DMG. Use when asked to update/upgrade the Natron MacPorts ports, run check.sh, reintegrate upstream Portfile changes, resolve failing Natron patchfiles after a MacPorts sync, regenerate Portfile.patch files, or build Natron / produce a DMG via tools/jenkins/launchBuildMain.sh. Enforces that lang/libomp stays pinned.
