+- `first-*` is the complete first viewport; `before-*` and `after-*` show the
+  requested comparison on desktop and at 390px.
+- After: comparison reuses the saved field translations; original records still
+  determine the version pair and four changed fields. Full originals remain
+  available in place.
+- `partial-*` intentionally omits a field and retains its original text.
+  The existing translation-coverage indicator stays available in the page header.

+The existing `research-display-language` browser scenario recreates these views
+and verifies originals, exact comparison selection, unchanged source-difference
+counts, invalid/missing/source/language fallback, citation return and read-only
+behavior. Its existing explicit execution-refusal case makes one rejected POST;
