//! Seed blog posts on each project (Phase 4).
//!
//! Drives the project blog page (`/p/{slug}/blog`) and per-project RSS
//! (`/p/{slug}/blog/feed.xml`). Posts are published (`published_at = NOW()`); the
//! owning project is already public and the creator non-sandbox, so they render to
//! anonymous fans. `body_html` is pre-rendered the same way the live blog handler
//! does (`render_creator_markdown`).
