A single focused feature today: repo summary chips across the top of the backlog. I wanted an at-a-glance count of what’s outstanding per repo without scrolling the whole list, so loadRepoSummaries aggregates item counts by repo, getBacklogSummary serves them, and a RepoSummaryChips component renders them above the ItemList, fed by a useRepoSummaries hook and fetchRepoSummaries. While I was in the request layer I pulled CSS serving out into its own createCssHandler, which trimmed a bunch of inline branching out of handleRequest and made room for the new endpoint without the handler getting messier than it already was.
