/* ── Toast stacking (Sonner-style), shared by both ports via data-stack ──────
   Both `ev::uikit` (Dioxus) and `@evinvest/uikit` (React) set data-stack on the
   toaster and drive the same machine: toasts are absolutely stacked at the
   pinned edge, pile up collapsed (front three peeking, each lifted + scaled by
   --index and clamped to --front-height), and spread to --offset on hover /
   keyboard focus (pure CSS — no JS state). Vars: the toaster sets --front-height
   + --gap; each toast sets --index, --z-index, --offset, --initial-height. React
   measures real heights; Dioxus can't (host-only), so it feeds a constant height
   — collapse is exact, expansion is uniform. The enter is a keyframe (plays on
   DOM insertion, so it works in both ports without a JS mount flip),
   `data-state=closed` slides out, and the node is dropped on the transitionend. */
