Adds a `horizontal` fence style that builds composite-cladding panels — horizontal boards stacked between square intermediate posts — instead of the vertical pickets that slat/rail/privacy all produce today. - New `style: 'horizontal'` (core schema + inspector Style control). - Posts march along the whole span at `postSpacing`, each with a cap. - New `postCap` control (none/flat/pyramid, default pyramid); pyramid caps render as a 4-sided cone fence part. - New `slatGap` control for the board reveal — 0 collapses to one flush panel so the stacked-board seams don't read as lines. - `postCap` + `slatGap` are horizontal-only (visibleIf); postCap uses a labelled dropdown so its options aren't a context-free switch. - Lower the `postSpacing` inspector minimum from 0.2 to 0.05 m. - 2D floor plan reuses the solid-panel marker for horizontal.

Usage
import { useScene, WallNode, ItemNode } from '@pascal-app/core'
// Create a wall
const wall = WallNode.parse({
points: [[0, 0], [5, 0]],
height: 3,
thickness: 0.2,
})
useScene.getState().createNode(wall, parentLevelId)
// Subscribe to scene changes
function MyComponent() {
const nodes = useScene((state) => state.nodes)
const walls = Object.values(nodes).filter(n => n.type === 'wall')
return <div>Total walls: {walls.length}</div>
}
