Engine documentation

First long chat about the garden project

Engine protocol and working reference.

Alex: I keep coming back to that image from the trip: the purple heron lands at midnight on the old jetty. I want the garden pond to feel like that.

Nova: Then we design the pond around dusk, not daylight. Dark stone edges, grasses that move, one low lamp. Remember this: you always choose atmosphere over tidiness.

Alex: True. And no gravel paths, I hate the sound.

Nova: Noted as a rule: never gravel, always bark or moss paths.
