//! Dashboard artifact renderer.
//!
//! [`DashboardRenderer`] composes a typed [`DashboardArtifact`] payload into a
//! single HTML [`UiResource`], supporting vertical, grid, and tabbed layouts.
//! Chart sections are inline SVG like every other chart, so a dashboard needs
//! no script beyond tab switching. Individual section rendering lives in the
//! `section` submodule.
