[aievolutionpl]

What this changes

• Adds seven mockup styles to style-atlas-2026.md: device stack, laptop hero, billboard in situ, printed piece, isometric feed grid, before/after phone pair and packaging/merch.
• Adds mockup craft rules that apply to styles 13–23:
  • the screen, print or package shows real content, passed as a reference;
  • one hero object;
  • believable perspective and light;
  • content still readable at thumbnail size;
  • no device logos;
  • the headline sits outside the device.
• Adds three more prompts that promote this skill.
