- CollapsedFilterRail: the byte-identical 31-line collapsed sidebar rail was in
both Sidebar (feed) and PlexSidebar → one shared component.
- VideoCard: the title + channel-button + meta block was duplicated across the
list-row and card layouts → a local `textBlock` element (only one layout branch
renders, so reusing the element is safe).
- subsColumn<T>(t): the identical 'subscribers' DataTable column in Channels +
ChannelDiscovery → a generic factory in channelColumns.tsx.
All behavior-neutral; jscpd now reports 0 clones (was 8 at Phase 0 baseline).
tsc + knip green.
