Body is the real <venact-options-editor mode="author">. The sticky topbar is the new element — scroll the panel and it stays pinned. Flip the toggle in the topbar: DEFINE shows today's DEFAULTS watermark on the value side; FILL greys & locks the whole DEFINITION column (left). The old in-body titles + per-row toggles are hidden to show the end state. Dial the values, then hit copy and paste the line back to me.
