The tour map stage and the trip planner page hook had grown past the complexity and length the lint ratchet holds them to. Marking a spot on a recorded paddle track moves into useTrackLinePick, and what the planner map frames into usePlannerFocusPoints, each with its own tests. The planner's viewport snapshot no longer reads a ref while rendering, so the count of that warning goes down by one.
