Estimate peak VAE VRAM usage in bytes

Description

Rough upper bound based on the largest intermediate feature map (conv layer with ~512 channels, f32). SDXL/Flux use wider channels.

Usage

.estimate_vae_vram(width, height, model_type = "sd1", batch = 1L)

Arguments

width	Image width in pixels
height	Image height in pixels
model_type	Model type string ("sd1", "sd2", "sdxl", "flux", etc.)
batch	Batch size (default 1)
