Correct the layers=0 output contract.
In all four pages, state that raw output is layers + 1, while template output is layers only when layers >= 1. With layers=0, LatentCut clamps index=1 to 0, so the template retains and outputs one full image. Use max(layers, 1) for the template count. The count must count.

| ### How the layers become separate images | ||
|
|
||
| The **Empty Qwen Image Layered Latent** node allocates a 5D latent shaped `[batch_size, 16, layers + 1, height // 8, width // 8]`. The layers sit on the third axis, the same temporal axis that video models use for frames. The **LatentCutToBatch** node with `dim` set to `t` moves that axis into the batch dimension, so after **VAE Decode** each layer is a separate image in the batch. | ||

Use one layer-index convention after the cut.
All four pages say that the full-image entry is removed before LatentCutToBatch, but later describe batch index 0 as the full image. State whether indices refer to the pre-cut latent or the post-cut decoded batch. The current wording can cause users to reorder or filter the layers incorrectly.

pricing.mdx (EN + zh/ja/ko): add the Gemini 3.7 Flash row to the Google Gemini chat table. The Gemini text node now exposes
gemini-3.7-flash(ComfyUI #15688). Pricing updated to align with current rates.startup-flags.mdx (EN + zh/ja/ko):
--enable-dynamic-vramnow defaults to auto on ROCm 7.14 and higher, in addition to Nvidia (ComfyUI #15633).qwen-image-layered.mdx (EN + zh/ja/ko): the image to layers workflow template now drops the duplicate first (full) image automatically with a
LatentCutnode, so the template outputslayersimages instead oflayers + 1. Updated the Layers and output section (ComfyUI #15364, workflow_templates #1092).Translation hashes synced for all three pages.
