Hostich/MindCare ? reverse-engineered prompt

Build me a simple Python web app called MindCare that feels calm and easy to use.

I want a clean home page, a way for users to sign in, and a few basic screens where they can record how they are feeling, add notes, and keep track of important reminders or appointments. Make it feel supportive and private, with a simple layout that works well on phone and desktop.

If the project needs any missing pieces, set up the app so it runs cleanly from the main entry file, use the existing config and migrations setup, and wire everything together so it actually works end to end. Please make the UI polished but not flashy, and keep the code organized so it is easy to extend later. If you need to check current docs or best practices for anything, go ahead and look them up online.
