Set Target dials, two-way cost calculator, offline-safe notes

Set Target uses snap dials, the cost calculator converts profit to points and back, and notes survive going offline.

• Set Target questions use a snapping dial plus an input box
• Cost calculator: profit wanted → points needed, and points → net gain/loss after charges
• Positions header fits one line on phone; closed trades are collapsible
• Auto journal stays off by default, with a ✕ on the card
• Notes are kept on your device if the network drops and sync when it returns
