// User playtest #5 item 7 — the Final Assault prep deploys on the player's half of the BOSS field (research 09 §1.2,
// official ConvertChessPositionInfoToBossMap / player_map_ud_offset 7): placement legality (server deploy map, the
// client's canPlace + legal-tile highlights, the bot) reads the boss field's tiles, not the normal field's.
//   User: "这张关底boss图靠右侧由1*3的管子框起来的地块官方原版是能部署干员的" — act2autochess_m01's 1×3 orange-railed
//   tiles (tile_fence_bound, LOW / buildable ALL) at boss (3–5, 8) and (3–5, 12) = board (10–12, 8) for both sides of a
//   pair; on the normal field board (10–12, 8) is '#' (tile_forbidden), which the remake used to read in R14 too.
// Audit: for every stage and every deploy field the server map equals the builder's official deploy tiles
// (stages.json deployTiles.normal / bossLeft / bossRight, from the level files' buildableType / heightType + devices),
// the client mirror equals the server, and nothing legal on the normal board becomes illegal in the boss round.
