+"""Add rsu_vest and rsu_offset columns.
+
+UK payslips for Meta report RSU grants as notional pay (gross inflation)
+and offset them via a same-magnitude deduction. The cash gross Viktor
+cares about for dashboarding is gross_pay - rsu_vest. Track both for
+reporting + exactness; cash and tax-rate charts compute from them.
