    Cash health check
    Stable, but watch the buffer
    • You currently earn more than you spend each month.
    • Your lowest projected balance is less than one month of expenses — a thin buffer if anything slips.
    12-month cash projection
    Shaded area is your base case. The dashed lines are explicit what-if scenarios (upside: revenue +20%; downside: revenue −20%, expenses +15%) — not confidence intervals.
