Docs: roadmap — A0 style-proof scene built (art progress 2026-07-14)

Phase-0 status + Workstream A0/A1 callouts: the in-engine ArtStaging style-proof
scene is built (prop+creature+suit triad under murk + light-is-territory pool
lighting, passes full/200px/grayscale); statics recipe validated in-engine;
skinned Rukhanka bake + 3 master shaders still open.

 1. **"CreatureKit" workflow/tooling:** one editor tool or hard checklist that takes a Blender export and yields a play-ready enemy — prefab with rig + ghost/network authoring + colliders + a tuning-table entry + spawn-table and bestiary hooks. **The measure: adding enemy N+1 touches zero undocumented steps.**
