          card 1 sticks at the viewport top with a full 100vh portrait.
       3. Continued scroll cycles through cards 2→6, each sliding in
          from the right while the previous one exits to the left.
       4. After card 6 is reached, the sticky releases and the page
          continues to the next section.
     To achieve step 1 the head must scroll naturally — which it
     cannot do while it lives inside .tn-trust-sticky. A small JS in
     each page moves `.tn-trust-head` to be a sibling BEFORE
     `.tn-trust-spacer` on mobile (and back inside on desktop), so the
     CSS below assumes head sits outside the sticky region. The mobile
     *_mobile.png bg image is designed portrait with an empty top band
     for the card's own number/title/desc text. */
