Two defaults moved by owner ruling (2026-10-07): the region blur doubles 20 → 40 (softer, wider cluster tints) and labelZoom drops 4 → 1 (node labels hidden at the overview, shown once the camera reaches fit zoom or closer). Stored values are untouched — only the absent-field fallbacks moved. The dead-center ladder law gains two owner-moved exceptions (labelZoom index 1, regions.blur index 7); every other default stays stop #5. 1428 tests, tsc, lint, build green.
