- lib/trading-logic.ts: computeDailyTarget() computes the next trading
day's profit target via two paths:
• No positive days yet → profitTarget × consistency (first day)
• Positive days exist → maxDay / consistency gives the total profit
needed to satisfy the consistency rule; target maxDay when far away,
or the exact remaining amount when close
- Account detail page: display "Next Trading Day Amount" in Objectives card
- Equity curve: add indigo dashed reference line for the consistency target
(maxDay / consistency), labelled top-left to avoid overlapping the amber
profit-target line (top-right)
