/* HYPERPART: hover-card */
/*
 * Rich preview on hover/focus/click — progressive enhancement.
 * Trigger + floating panel opens on:
 *   :hover / :focus-within  — fine pointers + keyboard
 *   [data-dz-open] / [data-open] / .is-open — controller (touch / click)
 *
 * iPadOS Safari does not keep :hover or button :focus after tap; relying on
 * focus-within alone made the gallery demo appear dead. controllers/dz-hover-card.js
 * toggles data-open on click/tap.
 *
 * Anatomy (canonical):
 *   .dz-hover-card
 *     .dz-hover-card__trigger
 *     .dz-hover-card__content   (alias: .dz-hover-card__panel — legacy)
 *
 * Hit-target: a transparent ::before bridge above the panel covers the
 * visual gap so the cursor can move trigger → panel without leaving
 * :hover on the root (classic "death zone" bug when top > 100%).
 *
 * shadcn parity (HMC-035). Distinct from popover (details exclusive open).
