Goal: Craft ancient totems by mixing materials to reach precise weight ranges. Balance exact percentage compositions of various materials to satisfy unique recipe requirements.

Controls: Add or remove material in specific gram increments using on-screen buttons. Adjust the "Step Size" to fine-tune the final mixture.

How it helps: This crafting simulation builds a deep intuition for ratios, percentages, and fractional parts, particularly in advanced levels that introduce prime-number distribution challenges.
