Clears the final 47 pairs and turns the ratchet into a hard gate
(AMBIGUITY_BASELINE = 0, assert_eq):
- HudButtons: the 14 HUD button/popover handlers run as one chain,
before ui_focus::FocusKeys — Esc/keyboard consumption order is now
defined (restore prompt → buttons/popovers → focus navigation →
settings toggle) instead of scheduler-dependent.
- HUD text updaters (update_hud, update_selection_hud,
update_won_previously) chained, in UiTextFx, after the new
AutoComplete set (update_hud reads AutoCompleteState).
- restore_hud_on_modal → apply_hud_visibility chained before
UpdateOnResize: HudVisibility writes, application, and the layout
read happen in a fixed order.
- New writer sets UndoRequestWriters / InfoToastWriters (same
self-ambiguous pattern as NewGameRequestWriters).
- Logic-before-paint: check_no_moves and the AutoComplete chain order
before BoardVisuals; SettingsMutation after UpdateOnResize.
- MarkerVisuals set wraps the table painter chain; chrome fx declare
disjointness from it.
- update_hud_typography after BoardVisuals; avatar/settings-toggle
interaction handlers declared disjoint from HudButtons.
302 → 198 → 171 → 47 → 0 in four batches, one day. New systems now
fail CI unless they declare their ordering or their disjointness.
Closes#143
