//! Everything drawn from board state, split by what it draws:
//!
//! - [`statics`]: the sand, the walls, the terrain, and the sprites that
//!   track tile contents (signposts, turnstiles, spawner holes).
//! - [`castles`]: the keeps, their pennants, and the shudder a bank sets
//!   off.
//! - [`water`]: the tide rising around the sand, and the foam on its edge.
//!
//! The shared bits, the sprite helper and the wall colour, live here, and
//! every module's public items are re-exported so the schedule and the
//! teardown code see one `board_render`.
