New Chalk biome & Graphite, new solid Palettes, Lighthouses and Archaeology

The "Chalk Cliffs" biome would generate along the coasts of oceanic birch islands. These would be striking white cliffs—tall with flat, grassy tops—composed of chalk blocks (which fall like sand/gravel), calcite, flint veins, and deep graphite caves. Chalk powder + honeycomb + standard game dye = new wax chalk blocks. These would be smooth, solid-colored, and pastel (mint green, baby blue, light pink)—perfect options for cute, soft builds. Graphite block + clay + dyes = lead blocks. These would be dark, elegant, and imposing (Cyan = Navy Blue, Magenta = Wine, etc.). *Both would come with their own slab and stair variants, including calcite.* A beautiful lighthouse would generate atop the biome, featuring redstone lamp lighting and a daylight sensor. Another rare structure would be a pirate hideout carved into the chalk walls, featuring checkered floors, mysterious decorations (skulls and black banners), and friendly nautical supplies (barrels containing wheat, sugarcane, sugar, honey bottles, and spyglasses). Suspicious chalk would also be present, dropping seashells and bones. Biome with a higher chance of yielding fossils. The Return of Nostalgia (Classic Flowers and Wool) Rare Flowers: The original Red Rose and the old Cyan Flower would generate atop the biome (decorative; they yield standard game dyes). Faded Wool Ball: A rare item found via archaeology or in pirate chests. It allows for crafting the deleted "Old Wools" (Capri, Chartreuse, Rose, and Ultramarine).
