    Historically four call sites constructed renderers when the
    user (or a default) picked a renderer class — SymbologyTab's
    installRendererClassIfChanged, KindRendererPanel::onModeChanged,
    Rule::setRendererById and SWMMResultsLayer's
    makeDefaultKindRenderer — and only one of them seeded the new
    renderer's base symbol. A default-constructed renderer carries
    an EMPTY base symbol; overrideColorInPlace only writes into
    colour slots that already exist, so symbolFor() returned a
    colour-less style and paint silently fell back to the legacy
    ramp. This factory is the single construction path: every
    renderer leaves it with an archetype-appropriate, fully-keyed
    base/fallback symbol and (when resolvable) a seeded classify
    attribute.
