/* Glossary tips — inline "?" chip that reveals a micro-definition.
 *
 * Reviewer's brief: "Every proprietary term needs a micro-definition
 * the first few times a user encounters it."
 *
 * Interaction model — accessible without JS:
 *   · hover the button       → tooltip appears (mouse)
 *   · Tab-focus the button   → tooltip appears (keyboard)
 *   · tap the button         → tooltip appears (mobile, native focus)
 *   · tap outside or Esc     → focus moves, tooltip hides
 *
 * The tooltip body is always in the DOM (aria-describedby target),
 * so screen readers always announce the definition — visibility is
 * purely a mouse/keyboard sighted-user affordance. */
