## 2026-07-06 视差定案（策划：远景夕阳要时刻在画面内）：背景是"远景天幕"，
|
||||
## 仅以 0.2 倍速随世界滚动（即 80% 跟随相机）——此前 0.92/0.8 的"近景层"
|
||||
## 参数方向反了，背景几乎钉在世界上，所以一直"看不出视差"。
|
||||
## 锚点 1734.5 = 让夕阳（原画 x≈760，世界 x≈1656）在出生点镜头（可见中心
|
||||
## 1340.8）恰好居中；相机全程 [1340.8, 2753.2] 内夕阳屏幕位置从中心缓移到
|
||||
## 左 282px，始终在画面内（已验算含光晕不出屏）。两端背景覆盖也已验算：
|
||||
## 极左窗 [880,1801.6]⊂[581.5,2882.5]、极右窗 [2292.4,3214]⊂[1711.5,4012.5]。
|
||||
## 已知取舍：步道砖烙在原画里会明显随镜头走（角色脚下滑动感），单张烙死图
|
||||
## 无解；美术把"近景步道"拆成独立 1:1 层后即可消除。勿用 Parallax2D
|
||||
## （历史上因 CanvasModulate/wipe 兼容性移除过，见 decisions.md）。
