Unicove 2.0 Component Architecture

Two repositories created simultaneously on July 16 establishing component-based architecture pattern:

Integration Stack:

greymass/unicove - Main application consuming shared components
greymass/unicove-components - Reusable component library providing UI primitives

Technical Relationship: Application-library split enabling:

Shared components: Button, Checkbox, CopyButton, Stack consumed by main application
Tailwind CSS v4 integration: Components use @source directive for style imports
Cross-project reuse: Component library designed for consumption by multiple Greymass properties
Independent development: Components can be developed and tested separately from application

Integration Pattern:

@import 'tailwindcss';
@import 'unicove-components';
@source "../node_modules/unicove-components";

Technology Stack Coordination:

Both repositories use Bun runtime
Both repositories use Tailwind CSS v4
Shared development workflows with Make

Impact: Architectural decision enabling code reuse across Greymass web properties while maintaining consistent design system. Foundation supported subsequent component development building on this library.
