/* ── TERM TOOLTIP COMPONENT ──────────────────────────────────
   Usage:
   <span class="term-tip" data-term="ai-debt">AI debt</span>

   The JS reads data-term, looks it up in GLOSSARY_TERMS,
   and shows a tooltip on hover (desktop) or tap (mobile).
   Each tooltip links to the full glossary entry.
