Phase 1 of default_layout_install_20260629:
- tests/artifacts/manualslop_layout_default.ini -> layouts/default.ini
(git mv preserves history; same content, new parallel-to-themes home)
- src/paths.py: layouts: Path field + SLOP_GLOBAL_LAYOUTS env override
+ get_layouts_dir() accessor (mirror themes at 60/83/150/210+)
- src/layouts.py: new LayoutFile @dataclass(frozen=True, slots=True) +
load_layouts_from_dir/file + load_layouts_from_disk consumer
(mirror src/theme_models.py + src/theme_2.py; Result drain per error_handling)
- tests/conftest.py:709: reads from layouts/default.ini
