@image1 is the exact character reference. Keep the same face, hair, body, skin tone, outfit and accessories every frame. Do not change identity or clothing. Style: vertical smartphone video, 9:16, 1080x1920. Raw handheld mobile footage at night. Realistic shake, motion blur, low-light noise, street-lamp lighting only. Maximum photorealism, filmed by a friend, not cinematic. Duration: 10 seconds. Audio: night park ambience, distant traffic, wind, candle crackle. Climax: wooden thunk, loud cork POP, champagne fizz, fireball WHOOOMP. Soft laughter at end. No speech, no music. Setting: ordinary city park at night. Dark sky, bare trees, warm lamps, dry ground, dead leaves, old wooden bench centered. Camera: handheld smartphone, waist-to-head framing. 00:00–00:01.5: Empty bench. Person enters from right smiling. Right hand holds dark green champagne bottle upright. Left hand carries small black cake with tall burning orange candles. 00:01.5–00:03: Sits center bench facing camera. Holds cake left, champagne right. Candles burning. 00:03–00:04: Shakes champagne vigorously with right hand. Cake remains steady. 00:04–00:05: Simultaneous action. Person slams the bottle’s flat bottom vertically onto the bench while turning toward the cake and blowing flammable powder across the candles. A huge realistic orange-yellow fireball bursts horizontally away from the face. 00:05–00:08.5: Extreme slow motion (1/8 speed). Cork shoots upward. Champagne erupts in a powerful 1.5–2 m fountain. Huge orange-yellow fireball expands above the cake with realistic flame, smoke, sparks and embers. Cake stays intact. Bottle remains vertical. Person holds pose, mouth open mid-blow. 00:08.5–00:10: Real time. Fireball fades into smoke. Champagne droplets fall on hair, clothes and bench. Fountain weakens but continues fizzing. Person smiles and laughs softly at camera. Constraints: same identity and clothing as @image1 every frame. Right hand always holds champagne, left hand always holds cake. No dropped props. Bottle strike and fire effect happen together. Fire moves away from face. Realistic fire and liquid physics only. No magic, sparkles, fireworks, confetti, text, subtitles or watermark.
