ADDED Requirements
Requirement: HTTP delivery applies compression and cache policy
The system SHALL apply transport-level compression and explicit cache directives for static assets, API responses, and public HTML routes.
Scenario: Compressed responses are available for eligible payloads
- WHEN a client requests compressible content that exceeds the compression threshold
- THEN the response is served with gzip compression
- AND response headers advertise the selected content encoding
Scenario: Route classes receive deterministic cache-control directives
- WHEN clients request static assets, API responses, or HTML page routes
- THEN each route class returns a cache policy aligned to its freshness requirements
- AND cache directives are explicit and testable from response headers
Requirement: Media rendering optimizes perceived loading performance
The system SHALL lazy-load non-critical images and render shimmer placeholders until image load completion or fallback resolution.
Scenario: Feed and modal images lazy-load with placeholders
- WHEN feed or modal images have not completed loading
- THEN a shimmer placeholder is visible for the pending image region
- AND the placeholder is removed after load or fallback error handling completes
Scenario: Image rendering reduces layout shift risk
- WHEN article images are rendered in hero, feed, or modal contexts
- THEN image elements include explicit dimensions and async decoding hints
- AND layout remains stable while content loads
Requirement: Smooth scrolling behavior is consistently enabled
The system SHALL provide smooth scrolling behavior for in-page navigation and user-initiated scroll interactions.
Scenario: In-page navigation uses smooth scrolling
- WHEN users navigate to in-page anchors or equivalent interactions
- THEN scrolling transitions occur smoothly rather than jumping abruptly
- AND behavior is consistent across supported breakpoints
