What and why

The Hidden Garden prologue now has its stage chunk, ready for Design review. It was drawn from the approved clean concept as a flat side elevation, 2160×720, with the concept's two figures removed. Two masked edits then added what the beats need; each changed only its own rectangle.

• The bench, where Dexter sits at the start (x ≈ 190–320). It's a little long, about 3 m.
• The wrong reflection. Below the end of the jetty, where Dexter points (x ≈ 1290–1323), the water mirrors a rusty girder with a ladder that isn't there. Its bottom edge is hard; that may help the "wrong" read, or it can be softened.

The path top is at y = 441. The jetty is the end of the walk: the shove into the pond (#50, #51) happens there.

Layers (layers.json, split by split_layers.py, exact): 03 rear · 04 water (the pond, as the issue asks) · 05 play (path + jetty) · 07 foreground (the reed silhouettes along the bottom). Everything above the path is one rear layer, and the foreground scrolls at 1.0 for now. Rectangles and colours would tear the big tree or the reeds at another speed, so sky/far/mid parallax waits for hand-drawn masks.

Short of the issue

• One chunk, not 2–3. I tried growing a start chunk to the left and an end chunk to the right with make_boards.py neighbour. Both came back with a different sky (mountains, a darker blue) that seams against the pond chunk, and the left one ignored the bench. Fixing that is the join repair in stage_art.py, a separate pass. One chunk is about 14 s of walking plus Dexter's beats; whether the prologue needs more ground is your call.
• No collision yet: that's [M3-S2] Annotate the Hidden Garden collision #85, on top of the checker in feat: add Rusty Creek collision with a reach checker #97.
