Function renderFieldNode

renderFieldNode(
    field: RenderField,
    value: unknown,
    ctx: RenderContext,
    surface: RenderSurface,
    rawProperties: Record<string, unknown>,
): HTMLElement | null
Renders one field to DOM, for a given surface.

An unknown widget yields null AND a runtime warning — decision Q9. It used to yield null in silence on one surface and a raw fallback on the other, so a typo'd widget was indistinguishable from a field with no value. It is never fatal: a bad profile must not blank the map.
Parameters
- field: RenderField
  Field descriptor, already projected to the render model.
- value: unknown
  Already-resolved field value.
- ctx: RenderContext
  Per-surface render context.
- surface: RenderSurface
  Which surface is being painted.
- rawProperties: Record<string, unknown>
  Raw feature property bag, for the taxonomy seam and the action payload.
Returns HTMLElement | null
The rendered element, or null.
