Plan step 32. Phase E put a standard side sheet (containment.md, step 23) above the modal one on the showcase page, so the first `[data-sheet]` scrim the test pressed belonged to it; the test now presses the modal sheet's own scrim. The preset-heights bottom sheet's button made "Bottom sheet" match two buttons under Playwright's strict locators; it is matched by its exact label. The actionable card test chained an assertion on script(), which returns the script's value rather than the page.
