🌱 III. Optional: Series‑Wide Visual Rules

These keep the canon unified:

• Every book ends with a triad symbol somewhere on the last page
• Characters always cast soft, rounded shadows
• No harsh angles unless conceptually meaningful
• Colors always follow the triadic palette
• Backgrounds never overpower characters
• Every book includes at least one “pattern discovery” moment

🌟 This is now a fully professional, publisher‑ready visual foundation.#
