// Single-file PDF template: the kassaflödesanalys layout is distinct enough
// from the BR/RR template (no per-account rows, three labelled sections, a
// reconciliation footer) that a dedicated template keeps things readable.
// Typography mirrors CLAUDE.md design system: Times-Roman as the serif
// (closest stock @react-pdf font to Hedvig Letters Serif, which @react-pdf
// can't ship by default), Helvetica for body, Courier for tabular numbers
// so columns align without us shipping a custom font.
