/* Mobile fix — the view() reveal is scroll-LINKED, so it is reversible: scrolling
   back up moves a stacked card down into its `entry` range and animates its
   opacity back toward 0. On short touch viewports with tall, full-width cards
   that transparent band covers much of the screen, so cards appear to "disappear"
   while scrubbing up and down. On mobile we therefore drop the scroll-driven
   reveal entirely and render every block statically visible (content first).
   Desktop keeps the entrance. This preserves the "never trapped invisible"
   guarantee — here it is simply always visible. */
