[Meta] Sass to PostCSS Migration Tracking

[seanwuapps]

This meta issue tracks the overall progress of migrating from Sass to PostCSS.

Main Tasks

1. Global Styles Migration ([Migration] Replace Sass with PostCSS: Global Styles and Utils #278)
2. Form Components Migration ([Migration] Migrate Form Components from Sass to PostCSS #279)
3. UI Components Migration ([Migration] Migrate UI Components from Sass to PostCSS #280)
4. Build Configuration Updates ([Migration] Update Build Configuration: Remove Sass Dependencies #281)

Timeline Suggestion

1. Start with [Migration] Replace Sass with PostCSS: Global Styles and Utils #278 as it's the foundation for other changes
2. Work on [Migration] Migrate Form Components from Sass to PostCSS #279 and [Migration] Migrate UI Components from Sass to PostCSS #280 in parallel once globals are done
3. Complete with [Migration] Update Build Configuration: Remove Sass Dependencies #281 to remove Sass entirely

Migration Strategy

• Gradual migration to minimize disruption
• Each component can be migrated individually
• Testing at each step to ensure visual consistency

Success Criteria

• All Sass files converted to PostCSS
• No Sass dependencies in project
• No deprecated warnings
• All tests passing
• Visual consistency maintained
• Build process simplified
• Documentation updated

This issue will be closed when all related issues are completed and Sass has been fully removed from the project.
