- Navigator stage: the next screen mounts hidden under the current one and is revealed only when its first data has arrived (ScreenGate held by useAsync/useGateHold), at most 450 ms; a thin top bar shows after 120 ms of waiting. Push slides from the left, back from the right, tabs only fade. - Session cache (stale-while-revalidate) for screen GETs: revisited screens draw instantly. - Home map and stats are fetched during the splash, so the first screen arrives complete. - Entrance pop-ins (mascot, islands, lesson cards) run on first view only, not on every revisit. - Shop status card shows placeholders instead of a wrong «نداری» while loading. - Re-tapping the open tab scrolls to top instead of reloading; sheets close with a swipe down. - Quiz: «۱ از ۴» instead of «۱/۴» (read as a fraction), varied praise, «N تا پشتِ هم درست», growth-mindset copy after a weak round, zero-reward tiles hidden. - Streak: a concrete next step when the streak is 0 or today is still empty. Checked in headless Chrome against the local backend (frame captures at 150 ms and 700 ms latency, rapid tab tapping, full quiz run). Not checked on a real phone or iOS Safari.
