Anti-rotation clip rail (piece 1 of 2) primary

Rail + fork + the back half of the hood. It goes on first: held flat on the frame face beside the rod (on the side away from the hinge), it slides sideways along the face so the rail passes behind the knob and its two back strips pass behind the rod just above and below the existing rod guide clip; its side tongue clicks onto one tab wing. The fork at its lower end takes the key on the housing collar. Reaction torque only. Print it with the clip latch as the first fit test. The rail length (clip_top_above_tip) is estimated from photo, not caliper: measure clip bottom to knob tip before trusting it.
