About
A straight 1.4 m wide flight climbing the full 3 m storey inside a 4 m bay: 16 risers, a sloped soffit, dark tread nosings and a two-rail guard on both sides. Dimensions 1.40 x 4.02 x 4.05 m (X x Y x Z). Origin at the foot of the flight on the lower deck datum; the climb runs toward +Z. Metres, +Y up, +Z front, ground contact at y=0. The base port sits on a lower deck edge and the top port lands on the upper deck edge exactly 3.00 m above it. Connectors: base (deck-edge), top (deck-edge). Sixteen risers at 0.1875 m with a 0.25 m going, so a storey is crossed in one 4 m bay. Neutral greybox palette for prototyping before art exists. Static geometry; no skinned rig, collision or navigation data.
