Parent Epic: #70
Priority: P1

Prerequisites

• 4.4: Create Story List Component #85 (4.4: Create Story List Component)
• 3.1: Create Stories Controller with RSC Rendering #78 (3.1: Create Stories Controller with RSC Rendering)
• 4.11: Create Loading Skeletons #92 (4.11: Create Loading Skeletons)

Next Issues (after this is complete)

• 7.3: Write Integration Tests (verify streaming behavior)

Acceptance Criteria

• Story list page streams progressively to browser
• Suspense boundaries properly configured in React components
• Loading skeletons show while stories are loading
• Page is interactive before all content loads
• Verify with Network throttling (slow 3G) in DevTools
• Rails controller sends chunked response

Implementation Notes

React on Rails Pro RSC streaming requires:

1. Controller configured for streaming responses
2. Proper Suspense boundaries in components
3. Loading fallbacks (skeletons) for suspended content

Test by:

1. Throttle network to slow 3G
2. Load story list page
3. Verify skeleton appears first, then content streams in
