Built-in demo samples

These PNGs power the HF Playground "Try a preset" examples in both the Synthetic Patterns tab and the Upload Masks tab. They are deterministic outputs of scripts/generate_demo_samples.py (run from the repo root) and are committed so the HF Space cold-start has no runtime tempdir dependency.

Slug	Pattern	Source
line_space	Line/Space grid	Synthetic, Apache-2.0 (this repo)
contact_holes	Contact array	Synthetic, Apache-2.0 (this repo)
sram_like	SRAM-like cell	Synthetic, Apache-2.0 (this repo)
random_logic	Manhattan logic	Synthetic, Apache-2.0 (this repo)

Each preset ships as two files: <slug>_target.png (clean design) and <slug>_pred.png (a perturbed prediction with intentional EPE > 0).
