note: Panel rendering/input surface (`crates/tui/src/multi_pod.rs` / Panel row selection/action display) が `00001KV4ZDMV1` と重なる可能性があるため、Alt+Enter Panel composer work の outcome 後に開始する。

note: `00001KV4YAAVY` と `00001KV4ZDMV1` を並行開始する。`00001KV4ZPAD3` は implementation_ready だが、Panel rendering/input surface の conflict risk と review/integration capacity のため queued のまま待機する。


summary: Accept Panel Ticket/Intake visual hierarchy improvement after Panel Alt+Enter integration. Improve primary/secondary row styling, child-row affordance, selection clarity, and bounded tests without changing lifecycle/registry/action semantics.

role_plan: Orchestrator creates dedicated implementation worktree and spawns Coder with write scope limited to that worktree. Reviewer will run read-only after implementation report. Prior conflict with `00001KV4ZDMV1` is resolved because Alt+Enter work is merged/validated/done.
