A notification's\n`severity` picks its icon and tone; its `displayType` picks the **surface** that\nrenders it β and each of the five spec types has a distinct one:\n\n| `displayType` | Presentation | Rendered by | Auto-dismiss |\n| --- | --- | --- | --- |\n| `toast` | transient overlay | the `onToast` delegate | yes |\n| `snackbar` | bottom-anchored bar, one at a time, one action | `` | yes |\n| `banner` | page-width strip in the content flow | `` | no |\n| `alert` | blocking acknowledgement dialog (FIFO) | `` | no |\n| `inline` | in place, at the raising surface | `` | no |\n\nThe surface components ship in `@object-ui/components`; mount them where they\nbelong (a banner is in flow, an inline notification sits next to its raiser).\n`onToast` receives **only** `toast` items β it used to receive all five, which is\nwhy every type looked like a toast.\n\n```tsx\nconst { notify } = useNotifications()\n\nnotify({ title: 'Saved', severity: 'success' }) // toast (spec default)\nnotify({ title: 'Viewing a draft', severity: 'warning', displayType: 'banner' })\nnotify({ title: 'Fix 2 fields', severity: 'error', displayType: 'inline', scope: 'contact-form' })\n```\n\nA surface component subscribes with `useNotificationsByPresentation(type, scope?)`,\nwhich also registers the surface β raising a `banner` with no banner surface\nmounted warns in dev instead of vanishing.\n\n`config` is the spec `NotificationConfigSchema` (`defaultPosition`,\n`defaultDuration`, `maxVisible`, `stackDirection`, `pauseOnHover`); the legacy\n`position` / `stacking` spellings still resolve through\n`resolveNotificationConfig`. Three helpers apply it so every surface agrees:\n`resolveNotificationPosition` (a declared position always wins; nothing declared\nleaves the surface on its own anchor), `visibleNotificationStack` (`maxVisible` +\n`stackDirection`), and the context's `pauseAutoDismiss` / `resumeAutoDismiss`\n(`pauseOnHover`).
