    "prompt": "Duration: 10s | Strict 16:9 Landscape | Native 4K UHD | 24fps. Genre: Cinematic Slice-of-Life Fantasy Comedy / Elemental Magic. Target: Ultra-realistic premium live-action fantasy cinema. Use @ image1 as the sole identity reference; preserve exactly as shown, ignoring only background, pose, framing, and text. Exactly one Character A, with no redesign, duplication, morphing, identity drift, outfit change, or hairstyle change. In an old witch’s kitchen, Character A attempts to make one cup of tea using elemental magic, but the spell becomes unexpectedly powerful. The scene begins with a table-level macro shot of a still ceramic cup of tea while Character A’s tired, unimpressed face remains softly blurred behind it. Character A reaches for the wand and raises it in profile. A thin orange-blue magical filament travels continuously from the wand tip through open space into the center of the tea, visibly making contact with the liquid and creating a subtle glowing ripple and warm reflection inside the cup; only after contact does the tea begin rotating. The stirring starts gently, then accelerates unnaturally fast, creating a small controlled whirlpool and a few droplets rising from the surface without splashing wildly. Character A watches with slightly widened eyes, then makes one quick reverse wand gesture to cancel the spell. The tea immediately becomes still. Character A lowers the wand onto the table, lifts the cup carefully, and takes one small sip. There is absolutely no disgust before tasting. After a brief beat, the excessive heat registers: Character A’s eyes narrow, brows pinch, nose wrinkles slightly, and the lips tighten into a restrained, exhausted grimace. Character A leans forward and spits the same mouthful of tea back into the same ceramic cup, keeping the lower face and cup visible together; show one small restrained spray of liquid leaving the mouth and landing back inside the cup, with no vomiting or excessive saliva. Character A then stares at the cup with quiet offended disbelief while lowering it toward the table, ending during the movement with no smile, camera look, victory pose, freeze frame, or fade. Camera language is cinematic macro depth with rack focus, tight profile, wand insert, readable over-the-shoulder magical contact, overhead tea-whirlpool detail, extreme eye close-up, and tight three-quarter reaction, maintaining consistent screen direction and avoiding chaotic camera shake or teleportation. Audio consists of quiet witch-kitchen ambience, wand ignition, a subtle magical hum, liquid swirling, cancellation sound, a small sip, restrained “ptuh,” soft liquid landing, and a disappointed exhale. Music is cozy, mischievous slice-of-life comedy using acoustic guitar, pizzicato strings, muted piano, playful clarinet, and brushed percussion, with no vocals; build gently during the magical stirring, briefly thin the score as the heat registers, then add one understated plucked accent when the tea lands back in the cup. Keep music below the sound effects and avoid boing sounds, circus music, meme sounds, or laugh tracks. Maintain strict causality: FILAMENT CONTACT → TEA STIRS → SPELL ESCALATES → SPELL CANCELLED → TEA STILL → SIP → HEAT REGISTERS → SAME MOUTHFUL SPAT BACK INTO SAME CUP → DEADPAN REGRET. Priority locks are identity, visible magical contact, continuous tea-state consistency, sip before reaction, the same mouthful visibly returning to the same cup, stable facial anatomy, restrained acting, realistic liquid physics, cinematic close-ups, and readable comedic timing. Negative prompt: duplicate character, duplicate cup, duplicate wand, duplicate tea, missing magical contact, magic hitting table or hand, reaction before sipping, new liquid appearing, whole cup spat out, vomiting, excessive saliva, broken mouth anatomy, premature stirring, instant violent whirlpool, large magical explosion, injury, identity drift, exaggerated acting, cartoon physics, anime, cheap CGI, plastic skin, discontinuity, frozen frames, subtitles, text, logo, watermark.",
