scrollTo/onScroll used the full screen width, but the ScrollView viewport is narrower
(card margins + padding), so the computed index desynced from the visible slide — the
last slide kept showing "Next"/"Skip" instead of "Start browsing". Measure the real
viewport width via onLayout and use it for paging, scrollTo and index. Caught on the
emulator (uiautomator dump — FLAG_SECURE blocks screenshots).

A 7-slide carousel shown once on first launch:
- the three tabs (Scenes/Movies/Sites)
- search, filters, saved searches, Performers/Tags/Favorites
- long-press actions (hide/duplicate a scene, remove a wrong performer, link diagnostics)
- player gestures (tap controls, double-tap ±15s, swipe to scrub, unmute)
- favorites, Hidden content, PIN lock, the ? report button, Sites ★ ratings
Gated by a SecureStore flag; replayable from Settings ⚙ → Replay tutorial (via a
tiny onboarding bus). Suppresses the What's-new popup for brand-new users (the tour
covers it) and marks the changelog seen on finish.
