/* AquaNetica Core: shared UI primitives.
 *
 * Every rule here is an EXTRACTION from AquaNetica Learning 1.19.0, not a
 * redesign. Values, breakpoints and transition timings are unchanged, so a
 * page migrating onto these classes should render pixel-identical.
 *
 * What is deliberately NOT here: anything course-shaped. Search, sort, the
 * facet sidebar and its drawer, the featured strip, card media band, provider
 * logo, provider label, the course metadata tag (Learning's .aqnl-pill), the
 * facts list and its icons all stay Learning-local. Visual similarity to a
 * future Business Tools element is not evidence that the component is shared.
 *
 * Requires tokens.css.

 * Page shell
 * Was Learning's .aqnl root, which carried the tokens AND the page shell on one
 * element. Those are separated here: .aqn (tokens.css) is the token and context
 * wrapper, .aqn-page is the shell. A future component that only needs AquaNetica
 * tokens must not silently inherit a 1200px measure and 56px/64px outer padding.
 *
 * A full AquaNetica page therefore carries both: class="aqn aqn-page".
