/* Dependency Review Console - MicroSim Stylesheet
 * ==============================================
 * Plain HTML/CSS (no vis-network): the card is two concept boxes joined by an
 * arrow, and the rationale text is the real content. CSS lays out prose better
 * than a canvas does.
 *
 * Rows: title / progress / edge card (flex) / fixed verdict / controls.
 * The verdict row is a fixed height so revealing a model answer never shifts the
 * classification buttons under the learner's cursor.
