/* Arbor Analytics — theme layer over vendored Bootstrap 5.3.
 *
 * Bootstrap 5.3 is driven by CSS custom properties, so the whole palette and type scale
 * are retuned here with no SASS and no build step. Loaded AFTER bootstrap.min.css.
 *
 * Palette comes from the deliverables themselves: the plan draws NRZ circles in green and
 * SRZ circles in brown, so the portal that produces them uses the same two colours. The
 * page sits on warm paper rather than blue-grey — this is a tool that makes printed
 * documents for council, and it should feel like one.
