/* ─────────────────────────────────────────────────────────
 * ANIMATION STORYBOARD — roster ⇄ dossier
 *
 *  browsing   five cast cards across the panel. Each card carries a
 *             `layoutId`, and each holds a drawn character rather than a photo
 *             — one vector that resolves at pane size and at thumbnail size.
 *  on select  the pressed card TRAVELS AND GROWS into the dossier on the left
 *             while the other four shrink into a two-by-two rail. Nothing
 *             fades out and back in: the four that stay are the same four
 *             elements, just smaller and somewhere else.
 *  switching  picking a thumbnail swaps the two — the new one grows into the
 *             pane as the old one shrinks back into the rail, passing each
 *             other mid-flight. That exchange is the interaction.
 *  details    name, team, powers and copy are NOT part of the morph. A shared
 *             layout animation cannot be steered, so they ride on top and
 *             arrive once the card has nearly landed, staggered by rank.
