About
An L-shaped stair: a 1.5 m flight climbing toward +Z, a 1.5 m square quarter landing on legs, then a second flight turning out along +X to finish one storey up. Dimensions 3.52 x 4.02 x 3.52 m (X x Y x Z). Origin at the centre of the stair cell on the lower deck datum; the first flight climbs toward +Z and the second toward +X. Metres, +Y up, +Z front, ground contact at y=0. The base port faces -Z on the lower deck; the top port faces +X on the upper deck 3.00 m above. Connectors: base (deck-edge), top (deck-edge). Neutral greybox palette for prototyping before art exists. Static geometry; no skinned rig, collision or navigation data.
