820 B
Age arrival platform
Newly created Ages place a 5×5 solid platform instead of cobblestone at their saved spawn. The block has full collision, renders as an opaque full block, breaks as easily as glass (0.3 hardness), has no loot table, and cannot be obtained with pick-block. Existing Ages retain their already-placed platform blocks, which adopt the new appearance and hardness without altering saved terrain.
The model reuses assets/rivencraft/textures/block/crystal_block.png, the 16×16 Legacy crystal tile. The former generated cloud texture is removed. The internal block ID remains rivencraft:cloud_platform to preserve saved worlds.
The separate decay provider protects the saved spawn area by position, so its protection remains in force regardless of the platform's material.
