+// Effect shapes:
+//   { stat, delta }                  instant shift of an indicator or economy variable
+//   { stat, delta, days }            shift spread evenly over `days` (then the value mean-reverts)
+//   { stat, delta, bias: true, days? } offset on the stat's *target* for `days` (permanent if omitted)
+//   { sector, delta[, days][, bias] } same, on a sector's quality
+//   { revenue: "income"|"corporate"|"vat", delta }  change tax rate (rate points), permanent
+//   { revenue: "other", delta }      change other revenue (% of GDP), permanent
+//   { oneOff: pct }                  one-time cost in % of GDP (negative = windfall)
+//   { extraSpending: delta }         permanent extra spending in % of GDP
