         (e.g., Spices -> Red Paprika, Yellow Turmeric, Brown Cinnamon. Tea -> Green, White, Oolong, Matcha).

     The Orbit:  Inlaid gold or brass rings ripple out from the center.
     The Planets:  Smaller mounds or spheres of the "Varieties" (Step 1) orbit the center, creating a colorful spectrum of textures (powders, grains, solids).

     The Origin (Top Corners):  Miniature dioramas sculpted directly onto the board showing the harvesting process (e.g., tiny figures picking tea leaves, mining gold, or shaking spice trees).
     The Journey (Bottom Corners):  Miniature dioramas showing the "Transit" (Step 1).
         Detail:  Use   Resin   for water (ships) or   Sand   for deserts (camels).
