"""
Preview driver for the Kuromi techno watermark.
Renders representative samples (dark / busy / bright backgrounds) so Quinn can
judge the look BEFORE the full batch. Produces, per sample:
- full watermarked image
- a thumbnail (card-width) render — the governing legibility case
- a bottom-right corner crop at 1:1 — to read fine detail
Plus an A/B/C comparison (Orbitron+plate / Audiowide+plate / Orbitron no-plate)
on the busy sample to settle font + plate-vs-glow in one round.
Outputs to: deployments/@domains/quinn.www/root/public/photos-watermarked/_preview/
