Fix:DetailSectionroutes a row whose resolved renderer type istextareatoTextAreaFieldwithreadonly(its ownwhitespace-pre-wrapread branch), ahead ofgetCellRenderer, with the value asString(coerceToSafeValue(value))so a string passes byte for byte and a non-string reads as the replaced cell drew it.TextAreaFieldwas already exported by@object-ui/fieldsand imported by plugin-detail, so no export moves (Clause-②: no) andTextAreaField.tsxis untouched; the grid's table mapping is unchanged.

Budget approved, needs legal review.with white-space nowrap (the card's exact reading); after = the stored value with both breaks and the trailing newline, white-space pre-wrap; atextcontrol with the same value stays one line. Interpretation stated in the PR: the ruling's 'a single-line value is unchanged' is pinned as 'reads back as the same text'; the cell no longer ellipsizes, so a long single-line textarea value now wraps, as the record form's read-only field does.",
