时长与镜头：原作是 30 秒、15 个阶段，每 2 秒一个新阶段。如果平台单条只能生成 15 秒，就拆成两条：第一条 0–14 秒（地基到树屋），第二条 14–30 秒（扩建到全景），第二条开头加一句"接着上一段的画面继续建造"，并把第一条的最后一帧作为第二条的首帧参考。

怎么填变量：[巨大的古树] 可换"[海边悬崖]""[雪山脚下]""[沙漠绿洲]"；建造内容按场景改，比如港口就写"码头、灯塔、渔船"。

常见失败与调整：

• 房子一下子凭空出现：最后的"关键规则"一定要留，它比时间轴本身更重要。
• 工人像复制粘贴：负面词里的"重复的工人"保留，并在正文加"工人衣服颜色、动作各不相同"。
• 看起来像玩具模型：加"真实材质，移轴摄影的微缩感，但不是玩具"。

Create a 30-second vertical 9:16 ultra-photorealistic miniature construction time-lapse: a spectacular village physically built around ONE enormous ancient tree. Hundreds of tiny realistic adult workers are visible continuously, working simultaneously with tools, ladders, ropes, carts and miniature cranes. Fast but readable construction, macro cinematic photography, natural sunlight, realistic wood, stone, soil, moss and vegetation, 4K HDR, live-action realism.

0–2s: Workers clear the ground, mark foundations and dig around the giant tree roots.
2–4s: Foundation stones and wooden floor beams are placed; workers erect the first timber posts.
4–6s: Wall panels, floorboards and support beams are assembled piece-by-piece.
6–8s: Workers lift rafters, build pitched roofs and place wooden shingles one-by-one.
8–10s: Teams climb the trunk and construct elevated platforms around the massive branches.
10–12s: Treehouses rise as workers install walls, windows, doors, balconies and roofs.
12–14s: Workers build wooden bridges and spiral staircases connecting the treehouses.
14–16s: More cottages are physically constructed outward from the giant tree, foundation-to-roof.
16–18s: Hundreds of workers lay stone pathways, fences and a small wooden stream bridge.
18–20s: A marketplace is assembled beneath the tree with stalls, counters and storage huts.
20–22s: Higher platforms, balconies and connected treehouses expand through the branches.
22–24s: Workers install railings, ladders, rope bridges, lantern posts and flower boxes.
24–26s: Teams place stones, plant flowers and trees, create gardens and finish winding paths.
26–28s: Final construction details are secured while hundreds of workers continue moving materials and working across the entire village.
28–30s: Golden-hour reveal. Tiny villagers cross bridges and paths as the camera smoothly pulls backward and rises, revealing the enormous ancient tree surrounded by the completed multi-level village.

KEY RULE: Every 2 seconds introduces a NEW visible construction stage while previous teams continue working. Buildings must visibly progress foundation → beams → walls → roof → details. No instant completion.

NEGATIVE: cartoon, toy, plastic, CGI look, magical construction, instant appearance, morphing, teleportation, floating objects, disappearing materials, duplicated workers, giant humans, children, anatomy glitches, changing tree, inconsistent architecture, empty scenes, text, logos, watermark.
