A highly realistic smartphone app screenshot mockup of a social media interface almost identical to X/Twitter, shown on an iPhone-style full-screen display with rounded corners against a dark blue-black background. The status bar at the top shows the time 9:41 on the left and cellular, Wi‑Fi, and battery icons on the right. The screen displays a French-language profile page for Marie Dubois, with a large cover photo of the Eiffel Tower and the Seine at sunset under a dramatic orange-blue sky. A circular profile photo overlaps the lower-left of the header, partially obscuring the face. A back arrow button appears in a dark translucent circle at top left, and a three-dot menu button in a matching circle at top right. Below the header, show the verified profile name Marie Dubois with a blue verification badge, the handle @MarieDubois, a short bio in French reading "Journaliste | Paris" on one line and "✨ Curieuse & voyageuse" on the next, then "Rejoint en mai 2012" beneath. Show follower stats in French: "1 245 Abonnements" and "32,8 k Abonnés". Add a tab bar with exactly 4 tabs labeled "Publications", "Réponses", "Médias", and "J'aime", with "Publications" selected and underlined in blue. In the feed, include exactly 3 visible posts. Post 1 is by Marie Dubois with blue verified badge and the French caption Balade matinale le long des quais de la Seine ☀️ #Paris #Promenade, followed by a 4-image collage in one row: 1) Eiffel Tower by the river at golden hour, 2) a Paris riverside walkway with a bridge and autumn trees, 3) a cozy terrace café with Eiffel Tower view, 4) a coffee cup beside an open notebook overlooking water. Below it, show engagement icons and counts: reply 258, repost 642, like 3,1 k. Post 2 is from verified news account "Le Monde" with handle "@LeMonde", black circular avatar with white monogram, and French text: "Dernières infos : Le nouveau gouvernement français a été annoncé 📰 Tous les details ici ↓" followed by a blue link "lemonde.fr/article123"; below it show counts 187, 512, and 2,7 k. Post 3 is from "Thomas Lefevre" with handle "@Thomas_Lf" and text "Juste incroyable ! 😍 Le Mont-Saint-Michel vu du ciel 📷", followed by a wide aerial photo of Mont-Saint-Michel. At the bottom, include an iOS-style navigation bar with exactly 5 elements: home icon, search icon, notifications bell with a red badge showing 4, messages envelope with a red badge showing 4, and a large floating blue compose button with a white quill/feather icon. Add the thin black iPhone home indicator centered at the very bottom. Use crisp modern UI typography, subtle gray dividers, realistic spacing, authentic X-like iconography, polished mobile app rendering, and near-photographic screenshot realism.
