@@ -17,7 +17,7 @@ Four usage scenarios:
 
 Rules:
 - An EMPTY STRING ('') as a value DELETES that translation (falls back to base language at runtime).
-- The 'enlace' field is NEVER translated by hand — the CocoEnlace engine maintains it; the PHP rejects it.
+- 'enlace' IS translatable: absolute path with the language prefix (e.g. '/en/contact/'). Note: when the base 'enlace' changes, CocoEnlace regenerates per-language rows and may overwrite it.
 - multitext fields are translated as the full serialized JSON string in a single row (translate the whole JSON value, not individual items).
 - prefix is the language code from list_web_languages (e.g. 'en'); do NOT write to prefix 'www' (base language is edited via normal record fields, not translations).
