/* Concept-term inline trigger — base styling.
 *
 * Renders correctly even before Phase J (concept-term.js) wires up the
 * click-to-open popover. Pages using
 *
 *   <span class="concept-term" data-term="cap-rate">cap rate</span>
 *
 * get the dotted underline + brass "?" cue and a hover affordance
 * immediately. Phase J's script upgrades each span to role="button" +
 * tabindex="0" + popover behaviour without needing to change markup.
