/* Behalf — Carbon & Linen
 *
 * The single source of truth for Resolve's visual identity. Every surface in
 * this service (ticket workspace, external-agent portal, website intake, ticket
 * view, component showcase) loads this file; none of them may define a local
 * palette, type scale, radius, or component language.
 *
 * Source: Behalf-Visual-Identity-Carbon-Linen.html, the section marked
 * data-look="carbon", using its final effective values. The reference board's
 * other directions and its presentation wrapper are not part of the identity.
 *
 * Character: restrained, near-monochrome cool gray, flat surfaces, crisp
 * 2px geometry, hierarchy from alignment/type/rules rather than colour or
 * shadow. The network motif is the only decoration.
 *
 * The --shared-* names keep their meaning from the earlier shared system, but
 * now resolve to Carbon & Linen values. Do not introduce a second palette.
