Golden Render Cases

These cases define reference scenarios future contributors must reproduce.

Required cases

• Image thumbnail + QR + footer URL.
• Text-only URL-art + QR at 8K.
• Very long URL requiring fit logic.
• Low-resolution uploaded image with crisp generated overlays.
• Localized UI labels in a long-language layout and in an RTL layout.

Reference behavior

Golden cases must be updated when canonical behavior changes, and old cases should be archived rather than silently replaced.
