    "incantation": "When adding structured context to a test step, pass `subtitle` and `params` in the `test.step()` options; reporters expose them as `testStep.subtitle` and `testStep.params`, and the trace viewer and HTML report display step context.",
    "examples": [
      "import { test } from '@playwright/test';\n\nawait test.step('Login', async () => {\n  // ...\n}, { subtitle: 'as admin', params: { user: 'admin' } });"

      "options.subtitle: String that complements the step title; reported as `testStep.subtitle`.",
      "options.params: Serializable object describing the step; reported as `testStep.params`.",
      "testStep.subtitle: Available subtitle; for Playwright API calls, the target locator or navigation URL; for `test.step()`, the author-provided subtitle.",
      "testStep.params: Available step parameters; API call steps may include a locator and call arguments, while `test.step()` steps contain author-provided parameters.",
      "Prerequisite: Use Playwright v1.63.0 or later; the docs mark `subtitle`, `params`, `testStep.subtitle`, and `testStep.params` as added in v1.63."
