Build a small symmetrical AFK room ...

Build a small symmetrical AFK room (17x11x9) using only full blocks (no slabs, stairs, entities, or leaves). Use mixed Stone Bricks, Mossy, Cracked, and Cobblestone for a cave-style structure with an open front. Center: glowing pile of Gold Blocks + Raw Gold Blocks with Glowstone inside. Left: Amethyst + Purple Concrete crystal. Right: Prismarine + Cyan Concrete + Sea Lantern crystal. Floor: Stone mix. Add simple benches with planks and wool. Keep it clean, blocky, and symmetrical.
