Single frame at 375 × 760. The desktop view is a 3-column comparison table (Standard / By-Job / Modified); on mobile that collapses to a single P&L list with a Standard ↔ By-Job segmented toggle. The By-Job view highlights the Field PT&I row that's been reclassified from OpEx into COGS.
By-Job moves the field portion of payroll tax + insurance above the COGS line for a truer gross profit. Net income is unchanged.
Single-column list replaces the desktop 3-column table. The segmented control swaps Standard ↔ By-Job in place; only the Modified math is shown when By-Job is on. The Field PT&I row gets a tan highlight + "RECLASSED FROM OPEX" badge so the CFO can see at a glance which line moved. Headline rows (Revenue, Gross Profit, Net Income) are larger and color-banded so the spine of the statement is scannable on a phone.
