    Sub-phase 8.13.6.2 STUB: this v1 stores rules (expression /
    symbol / label / scale range) and JSON-round-trips them, but
    expression evaluation is deferred to Slice **BI.2** (the label
    engine introduces the LabelExpression DSL parser, which this
    renderer reuses per §J.7). Until BI.2 lands, symbolFor() returns
    the fallback symbol.

    Storing the rules now keeps `.oswp` files written by a future
    build forward-loadable today (and vice versa). The full Map
    Symbology Dialog editor is deferred to Slice **BI.3**.

    Cross-slice: Slice BI Phase 8.13.6 (see GUI_IMPLEMENTATION_PLAN.md
    §J.2). Sub-phase 8.13.6.2 — stub.
