/* ================================================================
   THE DRILL ⋯ MENU, THE FEEDBACK DIALOG, THE THUMBS — practice/drill-menu.js

   The ⋯ is a SQUARE WITH ROUNDED CORNERS (Seth, 2026-10-28), at the far
   right of the question. The dialog copies claude.ai's feedback dialog:
   bold title, an optional issue select, an optional details box with an
   accent focus ring, a small italic line about what is sent, then Cancel
   (quiet) and Submit (solid, strongest ink). Theme tokens only
   (styles/variables.css): nothing here may be a raw light-on-dark colour.
