// Systematic row-alignment auditor (design governance tool).
//
// For every e2e-fixture fixture, finds horizontal clusters of interactive
// controls and reports:
//   - height mismatch  (same control type sharing a row)
//   - centerline drift (mixed control types sharing a row)
//   - radius mismatch  (same-row controls on different radius families;
//                       role=switch is pill by design and exempt)
// Usage: node scripts/audit-alignment.mjs   (expects a built renderer)
// Rule of thumb: mixed types align CENTERS; same types also match heights.
//
// Deliberate change from the original raw-spawn launcher: fixture windows now
// launch through `withFixtureWindow`, which means MAKA_E2E=1, a throwaway
// userData dir, and a sandboxed $HOME. The audit used to run against the real
// userData path — a developer with Maka open lost the single-instance lock —
// and could enumerate the real `~/.maka/skills`. Fixture pages render fixture
// data either way, so control geometry is unaffected; the isolation is the
// point.
import { withFixtureWindow } from './fixture-window.mjs';

// Each fixture names the element that means "this surface has rendered", so
// the audit never measures a half-mounted page. The module pages share one
// shell (`.maka-module-main`), every settings scenario mounts the settings
// modal (`.settingsSurface`), and turn-narrative is the chat surface.
