The first step of the C++ rewrite of the app: with the Python on its way out, "native" stops meaning anything. - src/core, src/style, src/tools: the reader and renderer, the style plugin and the tools, unchanged - CMakeLists.txt, build.sh, check-abi.sh, fuzz.sh at the root; build trees in build/<mode>-qt<N>/ and build/fuzz/ - tests/core: test-core, the fuzz targets and their vectors - tests/oracle: the XP-VM tooling (styles_matrix, conformance, export_check, the control jobs and the synthetic scheme) - native/README.md folded into the root README, with the new layout Verified from the new places: test-core (Qt 6 and 5), the style matrix (unchanged, 113/120 per visual style, 111/120 Classic), export_check, and a release build through check-abi.
