-- FS25_MasterHUD - mod entry point
-- =========================================================
-- Author: TisonK
-- =========================================================
-- Loads the MasterHUD modules, publishes the g_masterHUD handle, and hooks
-- the FS25 mission lifecycle:
--   Mission00.load          -> publish the cross-mod bridge handle
--   FSBaseMission.draw       -> the single ecosystem draw loop
--   FSBaseMission.mouseEvent -> route clicks to interactive panels
--   FSBaseMission.delete     -> free the shared overlay + drop the handle
--
-- Load order: MasterHUD is mod 3 (after StateLedger and NetworkSync). The
-- handle is published as soon as this file runs so companions loading after
-- it can register during their own module load.
