Overview

A receipt template: paper geometry plus a jsonb layout of positioned elements.

Hosts may subclass this to attach their own concerns — audit trail, archivable status, tenancy — and point config.template_class at the subclass so the gem's own queries return host instances. inheritance_column = nil keeps the subclass sharing this table with no STI type condition and no type column to maintain.
