  [TOPIC] Playground
  [DETAILS] Scratch pad for temporary notes, experiments, reminders, and half-formed ideas discovered while authoring or auditing skills — not a canonical rule file, do not cite from other skills. Kept as a durable sandbox so small observations don't clutter commit messages. Periodically pruned by hand; if something here becomes load-bearing, graduate it into a proper numbered skill leaf. Use only during active skill-authoring sessions as a drafting surface.
