   04-animations.css — Keyframes, Transitions & Motion
   ─────────────────────────────────────────────────────────────
   Central library of reusable @keyframes plus the overlay,
   toast, and modal components that depend on them.

   Sections:
     • @keyframes            (backdrop, modal, toast, spinner,
                              search, slide, shake)
     • .zimam-modal-*        (backdrop, container, header, body)
     • .zimam-toast-*        (container, icon, progress bar)
     • .zimam-search-*       (overlay, input, results)
     • .zimam-spinner        (loading indicator)
     • .zimam-confirm-dialog (confirmation overlay)

   Depends on: 01-tokens.css (colours, z-index, radius, shadow).
   Consumers: ConfirmDialog, ToastContainer, SearchOverlay,
              BaseDrawer, ModalBase — via ::deep or global class.
