Classic now renders through buildRenderModel, computeFrame, the template and renderCore, with S.No and HSN/SAC columns, GST slots only through checked Slot components, taxable value, reverse-charge line, cancelled tag, continuation band and Page n of N. Letter absorbs its height deficit in elastic gaps. A harness runs 15 fixtures on A4 and Letter plus an item sweep and asserts zero audit errors, repeated headers, no split blocks, rupee extraction and deterministic output. The legacy InvoiceDocument is removed.
