## 二、背景图（8，App 竖屏 9:16，SD1.5 长边 ≤768）

| key | 场景 | 美术方向 |
|---|---|---|
| bg_yongdao_wuchang | 午场泳池 | Empty weekday indoor pool at noon, glass ceiling light patterns rippling on the ceiling, lane 7 calm and unused, chlorinated blue, minimal, serene |
| bg_fendao_xian | 分道线 | Lane divider close-up at water surface, overlapping ripples, refracted sunlight caustics, blue gradient, minimal abstract realism |
| bg_daokou | 道口两人 | Two swimmers standing at a lane entrance with water splitting before them, seen low from water level, noon glare, restrained composition |
| bg_chubi_tongkuang | 触壁同框 | Two swimmers touching the pool wall at the same moment, lane line wavering between them, water caustics, symmetrical tension |
| bg_shenshui_qiang | 深水端 | Deep end of a 50m pool, pool floor tiles fading into dark blue depth, a swimmer holding the lane line, vertical light shafts, quiet dread |
| bg_chiyan_bingpai | 并排挂池沿 | Two swimmers side by side holding the pool edge in shallow end, calm water, arms parallel, afternoon light, quiet companionship |
| bg_zuihou_tang | 最后一趟 | Final lap: long shadows across water, single swimmer mid-stroke toward the deep end, surface light streaks, cinematic |
| bg_qingshang_qianshui | 清场 | After closing announcement: empty pool with water still trembling, bench with goggles and a prescription card, two pairs of slippers side by side, warm exit light |

## 三、BGM（1）

| key | 用途 | 音乐方向 |
|---|---|---|
| bgm_shuisheng | 全剧 | Underwater ambience bed: muffled filter-room tone, faint bubble texture, no melody, 60s loop；情绪交给 SFX 层 |

## 四、SFX 清单

划频与换气（近/远两版）／触壁手拍／水线拍打／夹板敲池沿／手表水下震动（闷）／急促换气（恐慌节拍）／池沿滴水／清场广播（带混响）／拖鞋脚步／拉链／棋——无。全部分层叠加，不用音乐推情绪（导演红线联动：卡片一拍禁配乐）。

## 六、主题曲（可选）

歌词意象须出自对话稿（水线、半米、夹板、数瓷砖、四十分钟、周三）；禁母题句（贴着别人的水走/借力作总结）。若做，放清场广播之后、拖鞋镜头——全剧唯一一次有旋律。
