+### Reusable dialog lines via `DialogLineLibrary` + `DialogLineRef`
+
+A single `DialogLineLibrary` asset (or a handful split by topic) holds `{ id → text }` entries. Every `EncounterDialogOption.text` is a `DialogLineRef` struct that resolves in this order:
+
+1. If the library reference + id resolves, use that.
+2. Otherwise fall back to `inlineText`.
+
+The drawer shows all three inputs plus a live preview of the final text — WYSIWYG survives. Designers prototype inline and promote common lines to the library later without changing the field's type.
+
+```csharp
+resolver.Register<SomeEvent>((evt, ctx) => {
+    var text = option.text.Resolve();  // library lookup, inline fallback, null if both empty
+});
+```
+
 ### Cross-table references via `EncounterLink`
 
 `EncounterLink` stores a table asset + stable `internalId` GUID. Rename-safe (the GUID doesn't change) and diffable. The custom drawer renders two dropdowns: first pick a table, then pick an encounter inside it.
