feature: ProjectSpire STS2 resource recovery workflow
I worked with GPT-5.5 on a reproducible Slay the Spire 2 resource extraction plan and then landed it in ProjectSpire across the recovery scripts, allowlist, generated resource subset, image-format experiment, and workflow docs.
The Principles matter more than the files: keep the full recovered dump local and ignored, track only curated resources with a current use, make extraction scriptable instead of manual, prefer readable Python tooling, keep binary assets repo-friendly with WebP and Git LFS, and write down the decisions close to the evidence.
