+  // painting (a late/superseded result is silently dropped) — after which
+  // nothing re-requests until the next keystroke, and the suggestion appears to

+  // no ghost text currently visible, we explicitly re-trigger inline suggest so
+  // the editor always eventually offers something for a settled cursor. The 2s
+  // window keeps this from firing needless requests during active editing; it
+  // fires at most once per idle period (triggering does not change content, so
+  // the timer is not re-armed by its own action).
