The boards stack becomes the root screen: Settings moves from its own tab to a sheet behind a leading gearshape button, the sort pickers trade their text segments for symbols (hand.draw, textformat.abc, clock) with the words kept for accessibility, and every list now opens sorted by most recent change. UI tests re-aimed at the gear button and Done-button scoping fixed for the sheet-over-sheet nav bars — 4/4 green in the simulator.
