Voxel world sound

The proposal gave the silent voxel world its sounds through one Web Audio graph: footsteps chosen by the block under the player, a landing, and the room's door opening and closing where it stood, with a volume in the world settings.

Why not: Every sound was keyed to a voxel world's parts: the block underfoot, the player's jump, the room's door. All of them are gone. The Genshin world has no character or door yet, and sound there is written as its own page when something in it makes one, not carried over from a world it no longer resembles.
