-- Driver: a quick directional tap should turn the player in place, not
-- also take a step (#415).  Player:tryMove (src/world/Player.lua) only
-- steps once turnTimer has counted down; TURN_FRAMES/turnFrames set how
-- many fixed steps a facing change blocks movement for before a held
-- direction is allowed to commit to a step.  This is an input-timing feel
-- bug: no assertion here can tell a quick tap from a held one the way a
-- human thumb can, so this hands the pad over rather than scripting taps
-- at a fixed, unrealistic frame count.
