/* A Relationship field's options as tiles (feat-096): the current platform's grid of icon buttons, drawn
   like the payment page's AmountButton. Each tile is the label of a native checkbox, hidden but still
   focused and read as a checkbox; the tick, not only the fill, says it is chosen (WCAG 1.4.1).

   Linked from both theme bases and from the dashboard's draft preview. The public design system's
   tokens come first; the dashboard has none of them, so each falls back to a Bootstrap variable. */
