+-- The three above are the desktop's, fixed. These four are the user's: each
+-- holds a named action from settings.json, or {} for unassigned, and the
+-- vocabulary is exactly the one custom shortcuts use -- actions.lua resolves
+-- both, through the same whitelist tables, so a gesture can no more introduce
+-- a command than a keybind can.
+--
+-- Nothing is emitted for an unassigned direction. That matters more here than
+-- it looks: a registration is read at config time and there is no way to
+-- remove one afterwards, so emitting a no-op gesture for every direction would
+-- consume the four-finger swipes permanently, including for whatever the
+-- compositor might do with them later.
+--
+-- Four rather than three because three is spoken for, and because four fingers
+-- is the largest number of them a touchpad this size can tell apart.
