# ==============================================================================
# H2 CORE PLATFORM v6.5  --  LVGL + 17 OreBolt OS Modules
# ==============================================================================
# v1.7 changes from v6.2:
#   * 17 .mod binaries + 1 standalone mapper daemon.
#   * proxalarm handles all proximity sensing (bledsp, proxvec, radar_ui).
#   * retro.mod is the retro game launcher.
#   * retro_input_mapper is a standalone uinput gamepad daemon (no LVGL).
#   * bledsp_poll_wifi() stub ready for future nl80211 integration.
#   * Only proxalarm needs -lbluetooth.
