// S1 compute (sceneseg-p150 OPT_PLAN S1, tt/subpixel.py): per output tile of the sub-pixel up-block, with the EPI
// LLKs (epi_compute.cpp):
// y = Zhi + Zlo add_binary_tile<NearestEven> (fp32 SFPU, operands unpacked to DEST as fp32)
// y = (y + Shi) + Slo (S1_SKIP: the composed skip conv's two products)
// y = y + bias the reader's bias tile (interior row or the border pattern of this row tile)
// y = gelu(y) gelu_tile<false> (S1_ACT 2: ttnn.gelu's exact erf form)
// out = bf16(y) typecast_tile<Float32, Float16_b> (S1_OUT_BF16)
// CT args: [0] R, [1] CT, [2] NC, [3] GX (work split as the reader: units u = c * R + r, contiguous per core).
// Defines: S1_ACT, S1_OUT_BF16, S1_SKIP, S1_ZLO (the Z lo product present: two weight terms), S1_SLO (likewise for
// the skip conv; round 4 P2: 0 = one weight term, no add, no CB).
