The Run tab gets a 'Second pass (upscale)' section: on/off, and the upscaled size by multiplier, target dimensions or megapixels with an alignment, the same arithmetic as Minimax H3 Latent Upscaler (3D). The planner outputs second_pass (BOOLEAN), upscale_width and upscale_height (INT); the graph does the latent upscale and the second sampling with its own nodes.
