/**
 * MCN Animations — Feedback (toasts, snackbars, undo)
 *
 * Studied from forevercomponents.com ("Toast Stack", "Undo Snackbar") and
 * rebuilt. Theirs are wall demos: they auto-cycle, and the toast stack has no
 * live region at all, so a screen reader never hears the message. Here a toast
 * is a real announcement:
 *
 *   - Each toast carries role="status" (polite) or role="alert" (assertive),
 *     so it is announced when it appears.
 *   - Every toast has a close button, and the auto-dismiss bar PAUSES on hover
 *     and on focus-within, and while the tab is hidden. That is WCAG 2.2.2
 *     (Pause, Stop, Hide) — you can always stop the clock and read it.
 *   - A toast with an action (Undo) defaults to no auto-dismiss at all: a
 *     destructive action must not commit because someone looked away.
 *   - Nothing here animates under prefers-reduced-motion; the toast simply
 *     appears and still dismisses.
 *
 * Usage (Oxygen: paste nothing, just call it from a Code Block or let the
 * Gravity Forms bridge do it):
 *   MCNAnimations.toast({ title: 'Saved', text: 'Changes synced', kind: 'success' });
 *   MCNAnimations.toast({ title: 'Item deleted', kind: 'warn',
 *     action: { label: 'Undo', onClick: restore }, timeout: 8000, onTimeout: commit });

/* --------------------------------------------------------------------------
 * Tooltip — .anim-tip
 *
 * Studied from forevercomponents.com ("Tooltip Pop") and rebuilt. Theirs is a
 * div that appears on pointerenter: no keyboard access, no Escape, no ARIA, and
 * it auto-pops on a loop. This is the criterion those fail, WCAG 1.4.13
 * (Content on Hover or Focus), and the reason the card module carries a comment
 * telling you not to build a detached floating tooltip:
 *
 *   DISMISSIBLE  Escape closes it without moving the pointer (JS).
 *   HOVERABLE    the bubble is a CHILD of the trigger and its hit area reaches
 *                back to the trigger, so the pointer never crosses a gap.
 *   PERSISTENT   it stays while hovered or focused; nothing times it out.
 *
 * The bubble also stays in the accessibility tree while hidden (opacity, never
 * visibility or display), because `aria-describedby` points at it: hiding it
 * the other way would take the description away from a screen reader.
 *
 * Usage (fx.js builds the bubble, so the builder tree stays clean):
 *   <button class="anim-tip" data-anim-tip="Move this case forward">…</button>
 *   <span class="anim-tip" data-anim-tip-from="#gfield_description_4_1">?</span>
 *   data-anim-tip-place="bottom" flips it under the trigger.
