Arrow

RB or slot releases on a CLEAN DIAGONAL toward the flat at a shallow angle (~25° from horizontal). Mostly lateral with a small upfield component — finishes ~2-3 yds deep, ~10 yds out (tackle_11 reference). No break, no settle. Outlet for the QB and a natural high-low partner with a sit/curl over the top.

Demo rendered on @X (outside WR) at 3yd depth. Only the route runner and the QB are shown so the break stays the focus; the same route family scales to any depth a play calls for, and concepts that use this route may set a different depth.
