serve-sim Placeholder Assets

Use this project-scoped skill when updating the not-running device preview images in this repo.

Workflow

  1. Read references/device-placeholder-assets.md.

  2. Run the audit script from the repo root:

    node .codex/skills/serve-sim-placeholder-assets/scripts/audit-placeholder-assets.mjs --out tmp/device-placeholder-assets

  3. Keep the public skills/serve-sim skill focused on end-user CLI usage; do not add this internal asset-maintenance workflow there.

  4. Update app code/tests only after reviewing the audit output for exact, fallback, or missing mappings.
