A pixel-perfect iOS light-mode quiz screen for a language learning app, shown in an iPhone 14 device frame. The screen shows an active multiple-choice question. At the top: a progress bar spanning the full width, 60% filled in sky blue, showing "Question 6 of 10". Below: a flame streak icon and "4 day streak" badge in orange-amber. The question card is a large white rounded rectangle with 16dp radius and a very light drop shadow: the question text reads "Which sentence uses the subjunctive mood correctly?" in 18px semibold dark gray. Four answer option buttons are stacked vertically — each is a white pill button with a thin sky-blue border and an answer letter circle (A, B, C, D) in sky blue on the left. Option B is in a selected state: the border is thicker indigo, the background is pale indigo, and the letter circle is filled indigo. A bottom "Check" button in full-width sky blue is active. Bottom tab bar: Home, Practice, Leaderboard, Profile.
