/*
 * Therapy & access topics (dev-076).
 *
 * The hub (/topics/), the three topic pages and the news topic chips. Scoped to
 * `.kl-topics` / `.kl-topic` / `.kl-news-card__topic` so no rule reaches another
 * surface. Every value comes from assets/css/tokens.css (no literal colour or
 * spacing), and the tables reuse the site's own `.kl-table--stack` card layout -
 * nothing here invents a table style.
