  "how": {
    "incantation": "When a test or inspection script needs a structured accessibility snapshot, call `locator.ariaSnapshotJSON()` or `page.ariaSnapshotJSON()`; pass optional `mode`, `depth`, or `boxes` options as needed. Both APIs were added in Playwright v1.63.0.",
    "examples": [
      "const snapshot = await page.getByRole('list').ariaSnapshotJSON();",
      "const snapshot = await page.ariaSnapshotJSON({ mode: 'ai', depth: 2, boxes: true });"
    ],
    "gotchas": [
      "Version: v1.63.0",
      "mode: `\"ai\"` or `\"default\"`; `\"ai\"` returns a snapshot optimized for AI consumption. Defaults to `\"default\"`.",
      "depth: Number; limits the snapshot depth when specified.",
      "boxes: Boolean; when true, adds each element's bounding box as a `box` property (`x`, `y`, `width`, `height`), in viewport-relative CSS pixels. Defaults to false.",
      "Prerequisite: Use Playwright v1.63 or later; both methods were added in v1.63."
