Ui Styling
Styling done via Elm records
Spacing, alignment, width/height as functions
No CSS class dependencies
Compositional styling with nested boxes
Text, color, and font properties controlled in Elm
State Management
Managed via The Elm Architecture (model-update-view)
UI state stored in model
Events update model via messages

No mutable state in elements themselves
Data Management
Immutable model data
JSON decoding/encoding for API calls
External data fetched via Http module
State updated via messages
Persistent state stored outside Elm if needed
