/*
 * Layout for the IBS/CBS tax simulator, ported from the original
 * standalone artifact. Every colour/space/type value here is a
 * var(--dash-*) token or a dash-design component class
 * (dash-card, dash-field, dash-input, dash-badge, dash-timeline) —
 * this file only adds the page-specific grid and grouping the shared
 * system doesn't already provide.
