/* A link inside a paragraph of prose must be distinguishable from its
   surrounding text by more than color alone (WCAG 2.2 SC 1.4.1, "Use
   of Color") - the base `a` rule above turns underlines off globally
   for nav items, buttons-styled-as-links, and card links, none of
   which need one (they're already visually set apart by position and
   styling). Underlining every <a> nested in a <p> is the standard,
   minimal-footprint fix that covers the actual failure mode (an
   inline link inside a sentence) without touching anything else -
   confirmed against the real running app via
   tools/accessibility_scan.py, this was a pre-existing gap the color
   refresh happened to surface, not something the refresh caused. */
