nijastp/trainup — reverse-engineered prompt

Build me a polished fitness and diet planning website called TrainUp. I want it to help people choose a fitness goal, share basic details like weight, height, activity level, diet preference, and available workout time, then get a simple personalized workout and food plan they can actually follow.

Make the site feel modern, friendly, and motivating. Include a clean home page, a form to create a plan, a results page with workouts, meal ideas, daily habits, and health tips, plus a simple dashboard where someone can review or update their plan. It should work nicely on mobile and desktop.

Please keep it practical and easy to use, not too complicated. Add sensible empty states, loading states, and basic error handling. Include a clear note that this is general wellness guidance and not medical advice. Use the existing client and server setup, wire everything together, and look up current docs online if you need to.
