+# =============================================================================
+# Giga + Age of Wonder Compatibility Patch — megastructure build-menu filter
+# Persistent on-screen "mode" button (see interface/zzzz_compat_megatab_bar.gui,
+# shown by events/zzzz_compat_megatab_events.txt). Cycles the build-menu filter:
+#   All  -> Giga only -> Age of Wonder only -> All ...
+#
+# State is two per-country flags (MP-safe, each player independent):
+#   neither            = All
+#   compat_mega_hide_aow  set = Giga only
+#   compat_mega_hide_giga set = AoW only
+# Megastructures' `potential` checks these (AoW via the shared
+# AOW_trigger_mega_potential override; Giga per-structure). The list only rebuilds
+# when the build window OPENS, so you set the mode first, then open the menu.
+#
+# Three buttons share one slot in the bar; the bound button_effect `potential`
+# (evaluated live, FROM = the viewing player's country) shows only the one matching
+# the current mode, so the button always displays the current mode and clicking it
+# advances to the next. ALL THREE also require NOT has_edict = compat_hide_megatab,
+# so activating that edict hides the button entirely (live).
