/* ---------------------------------------------------------------------------
   In-product explainers — the <info-tip> disclosure and the glossary page.

   Accessibility notes that are load-bearing, not decoration:
   · the panel is NEVER revealed on hover — it opens on click/Enter/Space only,
     which sidesteps WCAG 1.4.13 (content on hover) entirely; once open it is
     hoverable, persistent and ESC-dismissible (see js/infotip.js);
   · the trigger keeps a visible :focus-visible ring at 3:1 against its
     surroundings, and its hit area is 24×24 CSS px (WCAG 2.2 target size);
   · every colour pair below is ink-on-paper from the brand palette and clears
     4.5:1 for body text / 3:1 for the trigger border;
   · the open transition is dropped entirely under prefers-reduced-motion.
