+## Container water-storage revision — 10 September 2026, v005
+
+Marcus asked to make the water tanks a shipping container. Replaced the exposed cylinders with a dark-green 20-foot container-style module (approximately 6.06 × 2.44 × 2.59 m), retaining two sealed water tanks inside. Added corrugated walls, cargo doors and locking bars, corner castings, inlet/outlet manifolds, pump and a first-flush component concept. The container enclosure is not itself the water-retaining vessel. The west end is a transparent inspection cutaway. The garden service path reaches the east cargo doors. Updated tour chapter 13, the plan and exterior/cutaway/overview renders. Product selection, structural/loading checks and hydraulic sizing remain future design work.

+# Container rainwater storage
+
+Replaced the exposed rainwater cylinders with a dark-green 20-foot container-style enclosure at the existing water-service area. Water is stored in two separate sealed internal tanks; the steel container shell is not used as the water-retaining vessel. Added cargo door hardware, corrugations, support piers, manifold/plumbing concepts, pump and first-flush component, and a west inspection cutaway. Kept the east cargo-door approach clear. Updated chapter 13 while preserving the 30-chapter tour and all other approved features.
+
+Verified both tanks fit inside the container bounds, old exposed-tank objects are absent, all captions match, the kitchen and no-table-tennis decision remain intact, and full render settings remain 2560 × 1440. Inspected actual Cycles exterior and cutaway renders.

 Blender has full editable geometry and Cycles materials. Saved render settings are 2560 × 1440 at 100%; web preview renders are made at 60% (1536 × 864). The user previously reported low playback FPS. `00 FAST TOUR - lightweight viewport` is a static simplified display; `DETAIL - full geometry for renders` is disabled only in the viewport. Cycles renders exclude FAST and use DETAIL automatically. For detailed editing, enable DETAIL and disable FAST. After moving or removing geometry, refresh the affected fast copies as well.
 
-The tour contains 30 five-second chapters. Space plays/pauses with the pointer over the 3D view; Shift+Left Arrow returns to frame 1. The current scene opens at the overview. Update camera positions and captions whenever a subject moves.

+Marcus requested that the water tanks become a shipping container. The visible module is a roughly 20-foot corrugated-steel container at (-25, -8), 6.06 × 2.44 × 2.59 m. Two separate sealed tanks fit inside; the steel shell is an enclosure, not the water-retaining vessel. The cargo doors are at the east end and the west end is a transparent inspection cutaway. Plumbing is kept off the door faces, and the service path approaches the east end. Current renders: container-water.png, container-water-overview.png and container-water-cutaway.png.
