    Sub-phase 8.13.6.2 STUB: this v1 stores the categories + per-category
    symbols + a fallback symbol, JSON-round-trips them faithfully, and
    returns the matching symbol for a given value (or fallback when
    missing). The full Map Symbology Dialog editor for adding /
    renaming / colouring categories is deferred to Slice **BI.3**.

    The stub is intentionally functional rather than a no-op: existing
    tests in the renderer test file can confirm full round-trip + paint
    behaviour, so when BI.3 lands its editor it inherits a working
    engine instead of having to build one from scratch.

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