"Monthly cash flow — tax impact (RSU excluded)" was already stacking
group A in normal mode but rendered as 70%-opacity filled lines — the
overlap made the total-per-month figure visually inaccessible.
Switch drawStyle to bars (100% fill, 0-width lineWidth, no per-point
markers) so each month reads as a single stacked bar whose top edge is
the total cash-side deduction. Add "sum" to legend.calcs so the
tax-year totals per series show in the legend table alongside last and
max.
Panel 11 (Tax & pension — monthly, RSU-inclusive) retains the line/
area style so the two panels remain visually distinct.
