EllesmereUI_Startup.lua

-------------------------------------------------------------------------------
--  EllesmereUI_Startup.lua
--  Runs as early as possible (first file after the Lite framework).
--  Applies settings that the WoW engine caches at login time, before
--  other addon files or PLAYER_LOGIN handlers have a chance to run.
-------------------------------------------------------------------------------

-- Apply the saved combat text font immediately at file scope.
-- DAMAGE_TEXT_FONT must be set before the engine caches it at login.
-- CombatTextFont may not exist yet here, so we also hook ADDON_LOADED
-- to catch it as soon as it becomes available.
