The top-bar focus timer was hard-coded to 3:00. It now has a caret menu to choose a length in 10-minute steps up to an hour (10/20/30/40/50/60 min); the default is 10:00. Picking a duration stops the timer and reloads the clock; the current choice is check-marked.
Changed
components/TopBar.tsx—SessionTimergains adurationstate and a dropdown (TIMER_DURATIONS), with outside-click close. Toggle/reset now use the chosen duration instead of the oldDEFAULTconstant; fixed the stale "resets to 5:00" comment.
