"""project stages, the feedback-complete marker, concept blurbs + thumbnails

Revision ID: b8d4f2a6c1e3
Revises: f7d2b09e5a13
Create Date: 2026-09-02

(held here until the hub owns it), the client's "Feedback complete" round
marker, and a line + a picture per concept so the review stage reads at a
glance.
