The gate in the palisade run: two braced pine posts 3.5 m tall carrying a head beam and a rusted cap, with a lit red warning lamp over the middle. Each leaf is seven boards on two ledges and a diagonal brace, hung on two strap hinges and swinging clear of its own post. Dimensions 4.10 × 3.75 × 1.34 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Damp conifer forest realism: wet concrete and corroded corrugated steel, weathered pine, dark bark and soil, deep needle green, olive canvas, gunmetal and machined steel, with five emissive colours (amber fire, white floodlight, green status, blue screen, red warning) that also form the loot rarity ladder. Rigid node-transform clips open, close turn named nodes on their own pivots. No skinning, no skeleton, no skin weighting, no collision or navigation data.
