/*
 * FIX 3 — Visual card overlap and hover on right column
 *
 * Root cause A (visual bleed): opacity:0 alone does not remove an element
 * from the compositor's paint layer. During the 120ms setTimeout gap in the
 * original switchVisual(), all three cards briefly had no .active class and
 * sat stacked at position:absolute; inset:40px — card 3 bled through the
 * modal boundary because modal-content had overflow:visible.
 *
 * Root cause B (hover broken): Cards without .active had pointer-events:none
 * in CSS, but inline styles set by the old JS (position, inset) could override
 * the expected layout, causing invisible cards to sit on top of visible ones
 * and intercept mouse events.
 *
 * Fix: Add visibility:hidden to inactive state with a delayed transition
 * (delay = fade-out duration) so the element is fully removed from hit-testing
 * AFTER it finishes fading. On activation, visibility:visible fires instantly
 * (0s delay) so the fade-in is visible from the first frame.
 *
 * The JS (switchVisual) no longer uses setTimeout — active is toggled
 * immediately and synchronously, eliminating the gap where no card had .active.
