/** Editable policy-header fields. coveragesJson (freeform legacy blob) is not

 *  service. `total` is legacy-dead data on migrated rows — list and sort code
 *  still uses netPremium — but the capture form writes it going forward, along
 *  with `tax`, from the arithmetic in premium.ts. Both arrive as plain numbers
 *  rather than being recomputed server-side: the printed policy is the record
 *  of truth and staff must be able to key its rounding verbatim. */
