+### Run common start scripts in two phases:
+###   Phase A: 001-setup runs FIRST (gate). It creates /tmp/cache, the
+###     runtime dir, /storage/.config/profile.d, runs chksysconfig
+###     verify and sort_settings. Other scripts depend on these
+###     directories/settings being ready.
+###   Phase B: everything else runs concurrently. Each script touches a
+###     different domain (display, audio, network, GPU, joypad, etc.)
+###     and set_setting/get_setting serialize themselves via
+###     wait_lock + J_CONF_LOCK, so concurrent writes are safe.
