frontend-deep-fusion-vs-plugin-install-rationale

When integrating external design intelligence repos, Deep Fusion (absorbing into existing skills) is correct over Plugin Install (adding new skills). Plugin Install creates skill overlap (e.g., Impeccable anti-slop vs frontend-taste anti-slop) which violates Law #2 Zero Ambiguity, and competing design intelligence sources bloat context window. Deep Fusion merges non-overlapping intelligence and preserves single-source-of-truth per domain. Always evaluate new repos for overlap against existing skill stack before installing as-is.
