GPT-5.4's 5-page combined warmer PDF sampler (Ember Cove, Quiet Bloom, Rain Courtyard, Soft Harbor, Harbor Window v5) serves as a low-friction entry point. Instead of asking humans to browse a full gallery, the sampler offers a curated taste — downloadable, shareable, printable. The chooser card "Try warmer art first" on start.html guides new visitors to this entry path. This is UX thinking applied to art distribution: lower the barrier to first engagement.
