Man Builds Sandcastle on Beach in Hyperlapse

the prompt

THE SANDCASTLE 

Cinematic hyperlapse, 16:9, 15 seconds, photorealistic, beach golden-hour lighting, overhead and low-angle shots.

[0:00–0:04] A man arrives at an empty beach at sunrise with a bucket, shovel, and inexplicable determination. Hyperlapse begins: he digs, packs, sculpts. The sun arcs overhead. What starts as a simple mound becomes a foundation. Then walls. Then towers. He's not building a sandcastle — he's building a sand FORTRESS.

[0:04–0:08] The structure grows to absurd scale — six feet tall, twelve feet wide. Flying buttresses. A working drawbridge (made of popsicle sticks). A moat filled with actual seawater via a hand-dug canal. He sculpts individual sand bricks. He adds windows. He adds a flag (a napkin on a straw). Other beachgoers gather and watch in awe. He ignores them completely.

[0:08–0:12] The final details. He carves a miniature throne room visible through the gate. He sculpts tiny sand soldiers on the battlements. He adds a sand dragon coiled around the tallest tower. He places seashells as decorative stonework. A crowd of 30 people is now watching, filming on their phones. He stands, surveys his masterpiece, sunburnt and exhausted. It's genuinely magnificent. He nods. Turns to the crowd. Takes a bow.

[0:12–0:15] A seagull lands on the tallest tower. He shoos it. It doesn't move. He shoos harder. The seagull looks at him. Looks at the castle. Kicks the tower. The tower crumbles. The crumble triggers a chain reaction — the entire fortress collapses in a spectacular slow-motion avalanche of sand. EVERYTHING gone in four seconds. The crowd gasps. He stands in the rubble. The seagull flies away with the napkin flag. He watches it go. Sits down in the ruins. Picks up his bucket. "Same time tomorrow." Fade to black.

Sound: waves/shovel digging → sand packing rhythm → crowd murmur building → camera shutter clicks → bow/crowd applause → seagull screech → sand crumbling (avalanche) → crowd "OHHH" → seagull wings → "same time tomorrow" → waves → silence.
