// Local (SSR) posts indexed by slug. The hub broker stream derives
// feature_image from raw frontmatter only, so it omits images for posts
// whose card image came from the spoke's richer derivation (body-image
// scan + slug-hash backfill). Merge rather than replace so hydrating to
// the broker stream never drops a feature_image the local snapshot had.

new Map(data.posts.map((post) => [post.slug, post]))
