"""
Phase 2 apply — trim 9 long meta_descriptions, keep og/twitter mirrored.

Reads new descriptions from phase2_desc.json (slug -> new meta_description).
For each post sets meta_description = og_description = twitter_description to the
SAME new value via a minimal ghst --from-json patch (+ updated_at for Ghost's
collision check). Touches nothing else. READ-ONLY against meta_title/body/etc.
