## MODIFIED Requirements

### Requirement: Build-time caching
WordPress posts, pages, and categories MUST be written into the repo-local content cache used by the site build.

If the WordPress fetch fails, the system MUST NOT crash the entire build pipeline; it MUST either:
- keep the last-known-good cached WordPress content (if present), or
- store an empty WordPress dataset and allow the rest of the site to build.

When the cache layer is configured and reachable, the WordPress ingestion MUST cache `wp-json` responses (or normalized outputs) using a TTL so repeated ingestion runs avoid unnecessary network requests and parsing work.

#### Scenario: WordPress fetch fails
- **WHEN** a WordPress API request fails
- **THEN** the site build can still complete and the blog surface renders a graceful empty state

#### Scenario: Cache hit avoids wp-json refetch
- **WHEN** WordPress ingestion is executed within the configured cache TTL
- **THEN** it uses cached data instead of refetching from `wp-json`
