"""Gemini 4 twins of the 8 cars Astra drew (15 Oct 2026 ~16:50 CET, operator: "re-do the cars Astra did, but with Gemini 4 now,
I want to see the difference"). Each twin gets Astra's FIRST brief and the SAME reference sheet (road cars: the v1 job from git,
before Astra's revision round), its own slug <slug>-g4 (own Blender dir on gex44, own card id) and status "candidate": shown in
the library and showroom, never picked by a game until the operator chooses.
