Hero is the big one; the rest are mostly trims.\n\nThe three lanes framing landed well in the user tests, so I leaned into it harder.\n\nTwo open questions:\n1. Should we keep the screener mention up top, or move it down so we lead with split inbox?\n2. The closing CTA still feels long. I attached two trims.\n\nWould love a 15-minute sync before Tuesday's ship.",
