@@ -43,6 +43,8 @@ Actualizacion 2026-05-14:
   marca `themeDimension`/`densityDimension` como legacy/custom fuera de UIX.
 - `src/uix/morfo/README.md` actualizado: fija `translations`, `commonRef`,
   registro via `registerMorfo` y `soma.runtime(...)` como contrato vigente.
+- Referencias legacy de `frontend` afinadas: su densidad se documenta como
+  vocabulario compatible para migracion, no como flujo desde `prefs.density`.
 - Commits nuevos empujados:
   - `694eb5c5` — `Clarify prefs projection contract`
   - `223cdf9e` — `Align sema docs with channel ownership`
