/* --------------------------------------------------------------- controls */

/* The length/mode selector is a segmented control and now uses the shared
   .seg / .seg__btn component (design-system.css §10.1) rather than a local
   pressed state on .btn. The previous rule here made "selected" mean an
   outlined button with an accent underline, while the same state on the
   homepage meant a filled accent plate — one interaction, two answers, on the
   two controls a visitor is most likely to meet in the same session.
   Markup: <div class="seg" role="group" aria-label="Test length">
             <button class="seg__btn" aria-pressed="true" data-mode="15">15 seconds</button> … */
