User noticed the auto-derived fence inspector was missing the legacy
panel's Length + Curve sliders, and the section labelling was wrong
(Posts → Structure). Both Length and Curve are awkward for the
parametrics field model:
- **Length** doesn't map to a single node key — it's derived from
`start`/`end`, and editing it moves `end` along the existing
direction.
- **Curve** maps to `curveOffset` but the slider's min/max are
bounded per-node by the chord length, plus updates need
`normalizeWallCurveOffset`.
Adds a `kind: 'custom'` field with a kind-supplied
`component: ComponentType<{ node, onUpdate }>`. The inspector mounts
it and lets the kind own rendering + update logic. `key` becomes a
free-form React key/label since it no longer needs to map to a node
property.
Fence parametrics now mirrors the legacy layout 1:1:
- Style (segmented controls + showInfill toggle).
- Dimensions (Length, Curve, Height, Thickness).
- Structure (Base Height, Top Rail, Post Spacing, Post Size, Ground
Clear, Edge Inset).
Length + Curve live in fence/inspector-editors.tsx.
