## Why

ClawFort currently lacks a formal SEO and structured-data specification, which limits discoverability and consistency for search crawlers. Defining this now ensures the news experience is indexable, standards-oriented, and performance-focused as the content footprint grows.

## What Changes

- Add search-focused metadata requirements for the main page and policy pages (description, canonical, robots, social preview tags).
- Define structured data requirements so the home page is represented as `Newspaper` and each news item is represented as `NewsArticle`.
- Establish performance requirements for transport and caching behavior (HTTP compression and cache directives) plus front-end loading behavior.
- Define UX and rendering requirements for image lazy loading with shimmer placeholders and smooth scrolling.
- Require markup and interaction patterns that are compatible with strict standards validation goals.

## Capabilities

### New Capabilities
- `seo-meta-and-social-tags`: Standardize meta, canonical, robots, and social preview tags for key public pages.
- `news-structured-data`: Provide machine-readable `Newspaper` and `NewsArticle` structured data for homepage and article entries.
- `delivery-and-rendering-performance`: Define response compression/caching and client-side loading behavior for faster page delivery.

### Modified Capabilities
- None.

## Impact

- **Frontend/UI:** `frontend/index.html` and static policy pages gain SEO metadata, structured-data hooks, and loading-state behavior requirements.
- **Backend/API Delivery:** `backend/main.py` response middleware/headers are affected by compression and cache policy expectations.
- **Quality/Validation:** Standards conformance and SEO validation become explicit acceptance criteria for this change.
- **Operations:** Performance posture depends on HTTP behavior and deploy/runtime configuration alignment.
