/* AMT Tracker — design system.
 *
 * Ported from wireframes/AMT-Tracker-Wireframes.html so the screens can carry the wireframe's
 * markup unchanged. Bootstrap 5 does the heavy lifting; everything here is either a token, a
 * Bootstrap override, or a component the wireframe invents (path cards, funnel flowchart,
 * AI banner, assistant panel).
 *
 * Class names deliberately match the wireframe's. Resist renaming them — the wireframe is the
 * spec, and a diff against it is how we check fidelity.
