FocusDown paywall copy test: draft previews

Drafts only, not live. Rendered in Superwall's editor at iPhone SE (375×667), 6.1" (390×844) and 6.7" (428×926). Nothing is cut off or overlapping that isn't already the same on today's live paywall. The date and price fill in automatically per user (trial end date, local price).

Note: on iPhone SE both the current and new paywalls scroll (the button sits below the fold until you scroll). That's unchanged by this test.
