Blender blockout for a render-to-real video pass

The blockout is the guide clip: the video model copies the camera path, framing, lens feel, easing, cut points, shot lengths, the position and scale of every mass, figure facing and every trajectory, and it invents the rest from text and images (materials, light, weather, what each proxy really is, faces, wardrobe, extras, sound). So the blockout has full authority over motion and layout and none over look. Ambiguity ruins the pass; crudeness does not: a bent lamppost comes back as a snake, loose limb blocks as extra people, an unmarked car driving backward. Fix identity in geometry first, in prompt text second, and judge the result on a synced side-by-side of playblast and video, never in the viewport alone. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.

REQUIRED BACKGROUND: scenario-blender-expert (execution channel, review loop, 5.2 API changes). Video generation: scenario-blender (the plugin's quote, generate and place flow), the scenario skill (connection, uploads, jobs) and scenario-seedance (reference-video fields).
