// to show nothing but the layer and `id 12345`. The server now resolves the
// cliloc against its own table and attaches `clilocName` (see
// docs/website/CLILOCS.md); a shard with no cliloc file configured sends none,
// and the layer fallback below is exactly what the sheet did before.
//
// A player-given `name` outranks the resolved type name — "Bob's lucky axe"
// should not be relabelled "hatchet" — and the server applies the same
// precedence, so this only re-states it for a profile that arrived with both.

// into words (null where the cliloc table had nothing, or is not configured at
// all). Prefer it, and keep the literal-only path as the fallback for a profile
// served before the cliloc table existed — a numeric entry with no resolution is
