    Completes the primitive trio (Marker / Line / Fill). Mirrors
    MarkerSymbolLayerSpec (Z.4) and LineSymbolLayerSpec (Z.5) for
    polygon geometry so subcatchments / catchment polygons / 2D mesh
    cells can be styled with the same rigor as points and lines.

    A single SimpleFill kind covers solid AND hatch fills via
    Qt::BrushStyle (SolidPattern, Dense1..7Pattern, HorPattern,
    VerPattern, CrossPattern, BDiagPattern, FDiagPattern,
    DiagCrossPattern, NoBrush for outline-only). This keeps the model
    simple — no separate HatchFill spec is needed.

    Canonical property keys (stored on SymbolLayer::props for the
    SimpleFill kind):
      - "fillColor"       → QColor
      - "fillStyle"       → int (cast of Qt::BrushStyle)
      - "outlineColor"    → QColor
      - "outlineWidth"    → qreal (px)
      - "outlinePenStyle" → int (cast of Qt::PenStyle)
      - "joinStyle"       → int (cast of Qt::PenJoinStyle)

    Property keys are stable — they survive .oswp round-trips.
    Data-defined overrides target these same keys.
