- BlocksBody's richable prop was declared and passed at all four call
sites but never read.
- RawSection was a single-use Section wrapper; inlined at its one call.
- makeSliceList/makeDonut took a kit they immediately voided; the
factories and all call sites (specs included) drop the parameter.
- seqOfMessageId/flowAnchor lost export keywords nothing imported.
- EVENT_ICONS shed the inject/model entries the icon short-circuit
renders unreachable.
