cv_process and helpers (frame_diff, extract_blob, find_centroids) now read diff_thresh, min_blob_px, max_move, max_missed, and line_offset from state.tuning instead of file-scope static const constants. The four thresholds are promoted to file-local constexpr defaults in cv.cpp (CV_DEFAULT_*) and are no longer part of the public cv.h API — external code can't depend on them. cv_process signature drops the line_pct parameter; callers use state.tuning.line_offset instead. This eliminates the drift hazard of having two sources of truth (DeviceConfig.line_offset vs CVTuning.line_offset); the former is deleted. main.cpp now calls config_load_tuning(g_cv.tuning) after cv_init on boot so previously persisted tuning survives reboot; logs whether tuning came from NVS or defaults. The legacy NVS key "line_offset" is intentionally left alone — harmless and flash_device.py may still write it during provisioning. Migration is out of scope. Tests: 12/12 passing (11 existing + 1 new test_cv_process_respects_runtime_min_blob proving the runtime-read path). Flash: 1,414,069 bytes (89.9%).
