-- Patch: views/inventoryWindow.lua -- the "this item has no actions" case.
--
-- Pressing enter/z on an inventory cell calls window.enableItemMenu(), which
-- builds the item's action list via modules/item/getActionsList.lua. That list is
-- filtered by per-action `condition`s, and getActionsList returns NIL when none
-- of them apply -- a plain reagent, say, which you can neither wield, drink, read
-- nor switch on. newItemMenu then returns nil, enableItemMenu returns nil, and
-- the game does *literally nothing*: no menu, and not even the sound.select click
-- it plays on success.
--
-- Sighted players see the absence of a popup. By ear that is indistinguishable
-- from a dropped keypress, so this says so out loud. The successful case is NOT
-- announced here -- accessibility/states/_itemgrid.lua reads the open menu.
--
-- ORDERING: like patches/slider.lua this replaces package.loaded, so it only
-- affects requires that happen afterwards. Safe for the same reason: states are
-- loaded lazily by states.lua, and applyPatches() runs before the self-test.
