/* NBOP interactive components.
 *
 * Loaded after nbop.css and built entirely on its custom properties, so the
 * palette stays defined in one place. Nothing here introduces a new colour.
 *
 * The restraint is deliberate and is a positioning decision, not a taste one.
 * Notebook of a COO carries the warmth and the personality. A body that says
 * it assesses people and publishes its own pass rates cannot look like a
 * funnel, so there are no gradients, no shadows for their own sake, no
 * animation that exists to feel expensive.
