Goal: Image Upload Component Implementation

Implement the 19 UI components specified in the UI Components document as production React components in the ux-prototype Canary library, with full Storybook stories, MDX documentation, and unit tests for each.

Context

The Item Image Upload project has completed its UX component specification phase. Three use cases are fully defined (GEN::MEDIA::0001, 0002, 0003), scoping is complete (22 scenarios), and the component architecture has been designed and reviewed. The next step is to implement these components in the ux-prototype Storybook library so that business stakeholders can interact with them and provide feedback.

Scope

Repository: ux-prototype (Arda-cards/ux-prototype)
Target directory: src/components/canary/ (atoms, molecules, organisms)
Supporting types: src/types/canary/utilities/
No backend integration — all upload workflows use mock data and delayed Promises. Backend connectivity will be added in a future phase.

Deliverables

For each component:

Production React component (*.tsx)
Unit tests (*.test.tsx) — Vitest + React Testing Library
Storybook stories (*.stories.tsx) — interactive Playground + specialized stories highlighting key interactions
MDX documentation (*.mdx) — prose overview, Canvas embeds, props tables
Barrel exports (index.ts)

Success Criteria

All 19 components implemented with correct props interfaces per spec
~115 unit tests passing
~79 Storybook stories rendering correctly
Storybook builds without errors
Linter passes with zero warnings
All barrel exports updated in src/canary.ts
