Rework the product preview section around three real screens captured at
deviceScaleFactor 2 instead of the previous 900 px shots taken at a 75%
browser zoom, which read as blurry.
- capture the conversation workspace, the agent customization page and the
visitor widget, then crop each one to a consistent frame
- drop the tight 480 px widget crop and its leftover gray strip
- restructure the preview section with one lead line and a caption per shot,
and fold the local start-up steps into a shorter quick start
- keep the browser overlay out of the captures and note the method in the
asset manifest
- finish the visible ReplyPier rename (sidebar wordmark, widget footer,
page title, login screen, demo page) so screenshots and UI agree
