/* /personalisierig — Tee-Abo step 1: one question per screen on every viewport
   (php/personalisierig2.php, js/personalisierig.js). Base, header, buttons and footer come
   from tz-funnel.css (its global prefers-reduced-motion rule stays in charge there).

   Stepper mode (html.pz-js, set by the page's head script before the first paint): the six
   questions and the completion step share one grid cell (.pz-stage), so the stage is as tall
   as its tallest step, the tiles sit at the same y on every question and nothing around the
   stage moves when the step changes. Inactive steps are visibility:hidden (+ inert from the
   script), never display:none. Every text slot that changes has its space reserved.
   Without JS (no html.pz-js) the steps stack as a plain form that posts natively.

   Calm layout: three groups per question (progress row, picture with question, answers), a
   640px column centred in the first screen from 768px, the answers as a list below 480px. */
