+# S90meow_launcherd - R3 Pro II Plan B app-launcher daemon (zero patch)
+#
+# Design (ANALYSIS.md §18):
+#   * PASSIVE daemon: never EVIOCGRABs, never injects events. Reads keys via
+#     EVIOCGKEY state polling (immune to any grab the player holds), touch via
+#     normal event reads on event1 (not grabbed). Zero interference with the
+#     player's own key handling.
+#   * Hotkey: hold PREVIOUS + VOL_UP together >=300ms -> app menu
+#     (cross-device: PREVIOUS is a GPIO key on event0, VOL_UP is an ADC key
+#     on event2. A two-key chord on event2 alone is impossible — its four
+#     keys share ONE ADC channel, so the old dual-volume hotkey can never
+#     register physically; see ANALYSIS.md §18.8).
+#   * Starts BEFORE S92_03_start_music_player (S90 < S92) so it is up early;
+#     the input devices are created by S11module_driver_default.
+#   * Stop sends SIGTERM; the daemon SIGCONTs a frozen player before exiting.
