MR. Twinkle

1. Data models and type definitions done
   Created core TypeScript interfaces
   • Defined UserLocation interface (latitude, longitude, accuracy)
   • Defined CelestialObject interface (id, name, position, magnitude, type)
   • Defined Star interface extending CelestialObject (temperature, spectralType, distance, size)
   • Defined Constellation interface (name, stars, boundaryLines, mythology)
   • Defined Configuration interface (twinkleModeEnabled, storytellingMode, lastViewPosition)

Written property tests for data model validation
- Tested latitude range validation (-90 to 90)
- Tested longitude range validation (-180 to 180)
- Tested magnitude values are numeric
- Tested spectral type format validation

1. Configuration parser and serialization
   Implemented Configuration parser
   • Created parseConfiguration function that validates JSON structure
   • Implemented field presence validation for required fields
   • Returned descriptive error messages for invalid configurations
   • Handled parsing within 500ms performance requirement

simple structure for MR. twinkie is code the login ui and basic web ui is done today.
