     Turbo 8 wraps Drive navigations in document.startViewTransition
     (enabled by <meta name="view-transition" content="same-origin">).
     The browser's default root crossfade runs ~250ms, which feels
     floaty; tighten it so navigation reads as snappy. Opacity-only
     (no slide) keeps it calm and avoids fighting the stay-board modal
     slide physics. One place to tune the whole-app feel. */
