Module display_source 

DisplaySourceCard + DisplayPreviewFrame — selected screen card shown in the tray record popover after capture-mode selection (M-UI.7 / AUT-127).

Pure presentation. SSR-stable: the preview is rendered as CSS-positioned divs (the “deterministic non-Wisp fallback” called out in the spec). A Wisp-backed PNG variant can land later via the existing wisp-export-stories harness.
