Redesign the GenAI Applied page — shift from code focus to journey-based narrative

[rvanmaanen]

The GenAI Applied custom page currently has too much code-centric content. Redesign it to focus on the journey a user would take:

• Structure as a learning path or progression (beginner → intermediate → advanced).
• Less raw code, more narrative about the experience and decision-making process.
• Visual journey map or flow diagram.
• Link to detailed code examples rather than showing them inline.
• Emphasize outcomes and real scenarios over implementation details.
