+Common 'props' keys (not exhaustive; passthrough accepted):
+  label, type, description, isRequired, isUnique, defaultValue,
+  minLength, maxLength, listType, optionsType, optionsText,
+  optionsTablename, optionsValueField, optionsLabelField, optionsQuery,
+  filterField, allowedExtensions, maxUploads, createThumbnails,
+  maxThumbnailWidth, maxThumbnailHeight, fieldWidth, fieldHeight,
+  adminOnly, charsetRule, charset, tipoTags, tipoAtributo.
+
+Destructive cases:
+ - 'newFieldName' renames the MySQL column (data preserved, but any hardcoded
+   reference breaks).
+ - Changing 'type' may coerce/truncate existing data (e.g. wysiwyg -> textfield
+   drops HTML). The backend returns 'warnings' in the response — surface them
+   to the user.
