+**Growth Model:** Annual increment declines linearly to zero; total size is the sum of non-negative increments. No negative growth: DBH and height never decrease. Mortality is compounded annually according to the schedule in the config. Continuous mode uses the analytical formula:  
+\( \text{size}(t) = \text{initial} + r_0 \cdot (t - \frac{t^2}{2T_m}) \)  
+This version is smoother and may yield slightly different results than the discrete sum, especially for short time periods or small Tm.
+
+*Species are displayed as "Rhizophora spp." and "Avicennia germinans" throughout the dashboard for clarity.*
