## About

# army-crawl
Stay flat on the belly and drag forward — the lowest crawl, for going under things. A `sequence` with a deep `root.y` drop and a slow forward translation.

## How
- Use a `sequence` with `loop:false` (frame `root` is ABSOLUTE — `z` grows slowly; compute forward from `state.position`+`state.faceDeg`, here origin facing +Z). Keep `root.y` very low (~-0.8).
- Prone pose: deep torso bend (`Spine:[45,0,0]`,`Chest:[25,0,0]`), arms reaching ahead (`LeftUpperArm:[90,0,0]`,`RightUpperArm:[90,0,0]`), legs splayed low (`UpLeg:[40,0,0]`,`Leg:[60,0,0]` both). Alternate arm/leg pulls.
- Slow `durationMs` ~2800–3400.

## Example
- "army crawl forward" (at x:0,z:0,faceDeg:0) -> `{"durationMs":3000,"say":"Staying flat.","sequence":{"loop":false,"frames":[{"t":0,"pose":{"Spine":[45,0,0],"Chest":[25,0,0],"LeftUpperArm":[90,0,0],"RightUpperArm":[90,0,0],"LeftUpLeg":[40,0,0],"LeftLeg":[60,0,0],"RightUpLeg":[40,0,0],"RightLeg":[60,0,0]},"root":{"y":-0.8,"z":0}},{"t":0.5,"pose":{"LeftUpperArm":[70,0,0],"RightUpperArm":[100,0,0],"LeftUpLeg":[55,0,0],"RightUpLeg":[25,0,0]},"root":{"y":-0.8,"z":0.5}},{"t":1,"pose":{"LeftUpperArm":[90,0,0],"RightUpperArm":[90,0,0]},"root":{"y":-0.8,"z":1}}]}}`
