Local operating contract

This is a vendored Impeccable skill with local workflow guardrails. Keep upstream behavior intact unless a local rule prevents repeat misuse.

Treat this skill as the single custom Impeccable entrypoint. Do not pair it with a separate guide skill.
Prefer project-declared live workflows over framework defaults. If a repo defines dev:live, use it before live sessions.
Never assume Vite's default http://localhost:5173/ is the target app. Confirm the actual app URL from a strict-port script, dev logs, terminal output, or the user's open tab.
Distinguish the Impeccable helper server from the app server: serverPort from live.mjs serves /live.js and /poll; it is not the page to design.
Keep .impeccable/live/config.json as project config when live mode is intentionally set up. Treat .impeccable/live/server.json and .impeccable/live/sessions/ as local runtime state.
After live cleanup, source files should not retain injected live.js, impeccable-carbonize-*, stale data-impeccable-* plumbing, or preview-only scoped CSS.
Preserve the official visual rules below. Local guardrails are about setup, lifecycle, and repo hygiene, not weakening design quality.
