-- ── Touchpad gestures ───────────────────────────────────────────────────────

-- GNOME's gestures, reproduced: three fingers sideways moves between
-- workspaces, three fingers up opens the overview, three fingers down closes
-- it. That is the same muscle memory the keybinds were built to preserve.
--
-- Registered unconditionally rather than behind a preference. Hyprland 0.56
-- dropped `gestures:workspace_swipe` in favour of this `gesture` keyword, and a
-- registration is read at config time -- so a toggle would need a reload to
-- take effect, which is worse than the nothing these cost on a machine with no
-- touchpad. What IS tunable at runtime lives in Settings: how far a swipe has
-- to travel, and which way round it goes.
--
-- open and close rather than toggle twice: with a toggle on both directions,
-- swiping up from an already-open overview would close it, and swiping down
-- would reopen it. GNOME does not do that, and neither does this.
