Plugins register modes (card, replaces, order, flag, players) and publish documents through reskate.throwdowns.ui: the setup page, the waiting card, HUD slots themed on the game's HUD_<theme>_* widgets, the match panel, flags and match restrictions. SmokeyDawg58's native plumbing (throwdown_menu.cpp and its .inl files) renders them and posts throwdown_ui events back. kit::flag is the one native flag registration. General services added for it: reskate.files, reskate.ui.dialog, reskate.skater push/hold/bone_cam, reskate.camera.pad_flight, reskate.physics competition, reskate.session.world, reskate.tricks feed/gesture, and world entities. His ten modes are now Lua in his plugin: the rules, referee and wire (td/rules, referee, wire), and every page and HUD document (td/ui*.lua). Extension/Modes and reskate.modes are gone, along with every race and 1-UP branch in the SDK. The plugin test drives each mode through kit events. A native setup page is never written to while it closes into flag placement: its rows are not republished, the stock page is put back once the exit is over, and the stock Players slider is left alone while a plugin flag is out. This fixes the crashes on the Deathrace button and on 1-UP's Confirm.
