/*
FNXC:TaskDetail 2026-06-24-00:00:
Snapshot of the task whose detail is shown in the main panel (Board card click → full-panel detail), plus its initial tab. Kept as a snapshot so the view survives a tasks revalidation. Exposes the setters so App can compose open/close with view navigation, and so the embedded detail can patch the snapshot on task updates (setTask accepts the updater form). Extracted from AppInner.
