// Client talent tables (天赋树) imported from the 4229938 config dump into
// paths.clientConfigs:
// · TalentTreeGamePlayConfig.json — the gameplay ids the talent panel is split into (1..5).
// · TalentTreeConfig.json         — one row per tree: how the client keys it (gameplay / job
// class / spirit) — see TalentTree.
// · TalentTreeTalentConfig.json   — one row per talent node: owning tree, point cost, max layer.
// Optional, like the economy tables: a missing file only disables talent point accounting instead
// of refusing to start. The server needs these numbers because the client's AskActiveGameplayTalentLayer
// only carries (gameplayId, talentId, addLayer) — no cost — so a server that wants to debit points
// has to know what the node costs itself.
