The 'filters' + 'filterManager' pair didn't reveal the schema-vs-selection split. Rename to reflect the actual roles: - FiltersStore / filtersStore → AvailableFilterStore / availableFilterStore - createFilterManager / FilterManager → createAppliedFilterStore / AppliedFilterStore - filterManager singleton → appliedFilterStore - mapManagerToParams → mapAppliedFiltersToParams Directories and file basenames follow the new singleton names. Public barrel signature updated; all consumers (Search, FontSearch, Filters, FilterControls) point at the new identifiers.
