/* ---------- hover tooltip (data-tip) — auxiliary info that doesn't need
   permanent on-page space: HS/CAS classification detail, etc.
   NOTE: this used to be a pure-CSS ::after on the trigger itself, but every
   glass panel (.card, .doc, ...) has `backdrop-filter`, which establishes
   its own CSS stacking context -- so the tooltip's z-index only ranked
   within ITS card, and the next glass card in DOM order (painted as a
   sibling stacking context) still drew on top of it regardless. Rendered
   into one shared node appended to <body> instead (positioned by JS in
   app.js), which has no ancestor stacking context to get trapped inside. */
