Tidal Terror 0.0.1

• Added Coral Cathedral: a deep ocean biome with giant branching, chalice, and sea-fan corals, irregular smaller colonies, dense coral gardens, sandy floors, and sandstone beneath.
• Added animated Coral Crushers, Cathedral Rays, Veilglows, and Shardbacks, with habitat-specific natural spawning and separate population pools.
• Added blue and sandy Coral Crusher skins; natural spawns choose by seabed clearance, while spawn eggs choose randomly.
• Added predator pursuit, telegraphed bites and charges, moving recovery, low-health escape, and safe regeneration for Coral Crushers.
• Added peaceful schooling and curiosity for rays, pulsing jellyfish groups and contact stings, and crab foraging, warnings, defensive pinches, and escape.
• Added four raw seafood drops, four cooked foods, furnace/smoker/campfire recipes, and custom transparent spawn egg artwork.
• Improved reef boundaries and flooding, removed unwanted reef bubble columns, and adjusted new shipwreck/ruined-portal placement to the seabed.
• Added deep-water spawning support for dolphins, turtles, and tropical fish in Coral Cathedral, and reduced drowned selection weight there.
• Added native behavior, navigation, spawning, structure, food, and model regression fixtures, plus documented art workflows and preview tools.

World-generation fixes affect newly generated chunks. Existing terrain and structures are not automatically regenerated or moved.
