/* ===== ACCESSIBILITY — WCAG 2.2 AA compliance =====
   axe-core audit (2026-04-16) flagged link-in-text-block on links
   that relied on colour alone to differentiate from surrounding text.
   WCAG SC 1.4.1 (Use of Color) requires a non-colour indicator.
   The rules below add a subtle underline to every <a> in text
   contexts (paragraphs, lists, breadcrumbs, last-updated metadata,
   footer copy, hero subtitle, competitor note, blog body). Explicitly
   excluded: nav anchors, CTA buttons, art-card entry links, region-card
   CTAs — these have their own visual affordance (background fill,
   border, or nav-row context) and are not 'in a text block'. */
