Add Latent Split node (2/4 spatial split) for ComfyUI

Splits a [B,C,H,W] latent into left/right or top/bottom halves, or four
quadrants. Model-agnostic (SD, SDXL, Flux / FLUX.1 Krea); preserves batch
dimension and noise_mask.

+# ComfyUI-Latent-splitter
+
+A ComfyUI custom node that splits a latent into **2** (left/right or top/bottom)
+or **4** tiles along its spatial axes.
+
+It is model-agnostic — it only slices the height/width of the `[B, C, H, W]`
+latent tensor, so it works with SD/SDXL (4-channel) and Flux / **FLUX.1 Krea**
+(16-channel) latents alike. A `1024×1024` image (a `128×128` latent) splits into
+two `512×1024` halves or four `512×512` quadrants.
+
+## Node: Latent Split (2 / 4)
+
+**Category:** `latent`
+
+**Inputs**
+
+| Input  | Type   | Notes |
+|--------|--------|-------|
+| `samples` | LATENT | The latent to split. |
+| `mode` | choice | `left / right`, `top / bottom`, or `quad (4)`. |
+
+**Outputs** — filled in reading (row-major) order:
+
+| Mode | latent_1 | latent_2 | latent_3 | latent_4 |
+|------|----------|----------|----------|----------|
+| `left / right` | left  | right  | — | — |
+| `top / bottom` | top   | bottom | — | — |
+| `quad (4)`     | top-left | top-right | bottom-left | bottom-right |
+
+Unused outputs (3 and 4 in the two-way modes) return `None` — leave them
+unconnected. Odd latent dimensions split with the extra row/column going to the
+second tile. The batch dimension and any `noise_mask` are preserved (the mask is
+sliced to match each tile).
+
+## Install
+
+Clone into your ComfyUI `custom_nodes` directory:
+
+```bash
+cd ComfyUI/custom_nodes
+git clone https://github.com/ethanfel/ComfyUI-Split-Latent.git
+```
+
+No extra dependencies — it uses the PyTorch that ships with ComfyUI. Restart
+ComfyUI and find the node under **Add Node → latent → Latent Split (2 / 4)**.
