       1. User enters the Trust section and sees the head (eyebrow +
          headline + subtitle) above card 1 — both in normal scroll.
       2. As they keep scrolling, the head slides up out of view and
          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 the sticky releases and the page continues.
     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. */
