Ports the system-atlas agent skill: one data.mjs file renders both an interactive isometric HTML map (progressive-disclosure chapters, moving data packets, question tracking by Q-ID) and a generated text twin (SYSTEM.md) for the repo. Why: architecture discussions that outgrow a single diagram — the skill encodes hard-earned rules (max 3 structures per chapter, shapes+labels, docs-policy ask before committing). Upstream 410 stars since Aug 20, VoltAgent-listed; complements architecture-diagram (static SVG) with an explorable, stateful artifact. - optional-skills/creative/system-atlas/: SKILL.md (89 lines), references/ (design language, process lessons), assets/ (build.mjs, template.html, data.example.mjs) vendored verbatim; LICENSE.txt (MIT, Harshyt Goel) - Live smoke: node --check both .mjs OK; node build.mjs produced atlas.html (41.5 KB) + SYSTEM.md from the example data, zero deps - docs: own catalog row + generated page + sidebar entry only
