// centralized configuration fixed values stored one place.
//
// Instead of hardcoding values
//
// This makes it easy to update the entire app by changing values in just one location.
//
// For example, changing primaryColor here updates every button, header, and highlight in the app.
//
// All user-facing messages are stored here making translation and text updates simple.
//
// Grid layout values are defined here so we can adjust the card view globally.
// Easy maintain
