/* Relationship-axis book theme (Tier-3 no-op).
 * The hue is owned by the Tier-2 condition palette in family.css
 * (body[data-condition="trauma"], AA-verified). This per-book file exists only
 * to satisfy the renderer's required meta.theme.css path and to hold any future
 * book-only overrides without touching the shared condition palette.
 * Built 2026-07-02, relationship-axis batch. */
