Three changes:
1. Split panel 1 (YTD overlay of 6 non-additive lines) into two accounting-
clean stacked-area panels side-by-side:
- "YTD sources": salary + bonus + rsu_vest + residual (= gross)
- "YTD uses": net + income_tax + NI + pension_employee + student_loan
+ rsu_offset (= gross, per validate_totals identity)
Green for take-home, red/orange for taxes, purple for pension, teal
for RSU offset — visually encodes "what you earned vs what was taken".
2. Panel 3 effective rate switched from per-slip attribution to YTD
cumulative (SUM OVER w / SUM OVER w). Kills the vest-month >100% spike:
the old SQL subtracted `rsu_vest × ytd_avg_rate` from income_tax, but
Meta's variant-C grossup means actual RSU tax is on `rsu_grossup × top
marginal`, not rsu_vest × average. Cumulative approach blends both
proportionally, no attribution hack needed. Also adds a third series:
all-deductions rate (income_tax + NI + student_loan / gross).
3. New panel 8 — Sankey (netsage-sankey-panel) showing sources → Gross →
uses over the selected time range. Plugin added to grafana Helm values.
