Troubleshoot document layout and overflow

Reproduce with a fixture

Capture a redacted data fixture and the exact immutable template version. Avoid debugging against a moving development alias.

Reduce the fixture while preserving the failure to identify the component or content boundary involved.

Check common causes

Inspect long text, unbroken strings, repeated array sizes, missing optional values, page dimensions, remote asset availability, and font glyph coverage.

Compare editor example data with the API payload structure.

Turn regressions into tests

Keep the redacted fixture in the staging suite and add a visual or semantic assertion before promoting the corrected version.
