Surveys get optional intro screen before first question

1.47.0

Minor Changes

• #4436 80f15a3 Thanks @jakesciotto! - feat(surveys): optional intro screen shown before the first question

  Surveys can now display an intro screen before question 1, configured via the new displayIntroScreen, introScreenHeader, introScreenDescription, introScreenDescriptionContentType, and introScreenButtonText appearance fields. The intro is dismissed with a button and records no response, does not affect completion or partial-response metrics, does not re-fire "survey shown", and is skipped when a survey is resumed with answers in progress. Intro copy is translatable like the thank-you message. renderSurveysPreview accepts previewPageIndex: -1 (exported as INTRO_SCREEN_PREVIEW_INDEX) to preview the intro screen. (2026-08-10)
