Static RENDER_BUFFER_DEFER_V_INC 

pub static RENDER_BUFFER_DEFER_V_INC: AtomicU32

Sub-knob: defer the $2007 v-glitch increment to the TStep dot.

The TStep is the SAME dot as the buffer reload — TriCNES PPU_DATA_StateMachine_Half: PPU_2007_TStep = TStep_Latch || PD_RB — instead of read time. With the immediate increment, every fetch in the read-to-reload window uses the post-glitch v (coarse-x +1 -> NT byte = tile+1; fine-y +1 -> PT row+1) — exactly the per-index mismatch signature the W2 baseline measured. 1 = deferred (default), 0 = immediate (legacy). Env knob RUSTYNES_2007_VINC (wired in the diag bins).
