You are using Claude Code to accelerate software development.

The defects are coupled, so changing all three simultaneously would make it difficult to determine which modification caused an improvement or regression. Option C establishes a controlled sequence: correct the foundational column geometry, verify the resulting layout, format dates within the stabilized columns, and finally tune page breaks using the resulting content heights.

Anthropic recommends tight feedback loops and early course correction. It also advises supplying Claude with an executable or observable verification mechanism, such as a test, build result, generated fixture, or screenshot comparison. Claude can then make a focused change, inspect the output, and iterate until that specific condition is satisfied. ( https://code.claude.com/docs/en/best-practices )

Option A discards useful context from the functioning database implementation. Option B changes multiple interacting variables in one pass, making failures harder to isolate. Option D provides a useful visual target but does not replace precise technical constraints or incremental verification.

Each stage should have explicit acceptance criteria—for example, minimum column widths, expected date strings, and page-break fixtures using short and long content. Once a stage passes, its test becomes a regression guard for subsequent changes.
