+    <p>Each condition concerns final actual alliance membership when this Nexus closes.
+      AND requires every condition; OR requires at least one. No negates the whole expression, not each condition separately.
+      Legal alternatives remain available; no fixed branch is selected for you.
+      Yes and No settle only at the actual Nexus close. Forming an alliance does not fulfill the answer early.
+      Offers alone are not alliances.</p>
+    <p className="fine">An owned Yes route needs an existing alliance or an actual reciprocal invitation.
+      Neither answer promises another player’s consent or prevents their original actions.
+      If future consent is needed, unknown may apply; the holder can ask again or save the card.
+      Honor any earlier promises first; their own controls handle required payments.
