/* Questions de fond (template/espace/questions-de-fond.php, 2026-10-17): the sea at night. The light comes from the
   surface and fades as the couple dives (--qf-depth: 0 at the surface, 1 at the bottom, written by the script);
   bubbles rise; at each dive the question goes up and the next one rises from below. The three views (a question,
   the wall of the Pass, the bottom) share one place in a stage of fixed size, so nothing around them moves. Only
   transforms and opacity move; still for those who ask for less motion. */
