## Purpose

Canonical specification for royalty-free-image-enrichment requirements synced from OpenSpec change deltas.

## Requirements

### Requirement: System enriches summaries with appropriate royalty-free images
The system SHALL attach an appropriate royalty-free image to each summarized article.

#### Scenario: Successful royalty-free image retrieval
- **WHEN** summary generation succeeds for an article
- **THEN** the system retrieves an appropriate royalty-free image for that article context
- **AND** stores image URL and attribution metadata for rendering

#### Scenario: MCP-preferred retrieval path
- **WHEN** MCP image integration is available in runtime
- **THEN** the system uses MCP-based retrieval as the preferred image sourcing path
- **AND** falls back to configured non-MCP royalty-free source path when MCP retrieval fails or is unavailable

### Requirement: Image retrieval failures do not block article availability
The system SHALL remain resilient when image sourcing fails.

#### Scenario: Image fallback behavior
- **WHEN** no suitable royalty-free image can be retrieved
- **THEN** the article summary remains available for modal display
- **AND** UI uses configured placeholder/fallback image behavior
