## Why

ClawFort currently publishes content in a single language, which limits accessibility for regional audiences. Adding multilingual delivery now improves usability for Tamil and Malayalam readers while keeping the current English workflow intact.

## What Changes

- **New Capabilities:**
  - Persist the fetched articles locally in database. 
  - Generate Tamil and Malayalam translations for each newly created article using Perplexity.
  - Store translated variants as language-specific content items linked to the same base article.
  - Add a language selector on the landing page to switch article rendering language.
  - Persist user language preference in browser storage (local storage or cookie) and restore it for returning users.
- **Frontend:**
  - Add visible language switcher UI on the one-page experience.
  - Render hero and feed content in selected language when translation exists.
- **Backend:**
  - Extend content generation flow to request and save multilingual outputs.
  - Serve language-specific content for existing API reads.

## Capabilities

### New Capabilities
- `article-translations-ml-tm`: Create and store Tamil and Malayalam translated content variants for each article at creation time.
- `language-aware-content-delivery`: Return and render language-specific article fields based on selected language.
- `language-preference-persistence`: Persist and restore user-selected language across sessions for returning users.

### Modified Capabilities
- None.

## Impact

- **Code:** Backend aggregation/storage flow, API response handling, and frontend rendering/state management will be updated.
- **APIs:** Existing read endpoints will need language-aware response behavior or language selection input handling.
- **Dependencies:** Reuses Perplexity integration; no mandatory new external provider expected.
- **Infrastructure:** No deployment topology changes.
- **Environment:** Uses existing Perplexity configuration; may introduce optional translation toggles/settings later.
- **Data:** Adds translation data model/fields linked to each source article.
