Render the three two-phase-flow summary tables correctly and align their phase labels, sentinels, and configuration masks with drainage, imbibition, and injection. Clarify the inverse-radius capillary-pressure relation and why injection pressure alone cannot reconstruct invasion history.

Validation: 409 unit tests passed, 3 skipped; all 51 notebook code cells passed with nbval-lax. Focused Sphinx/MyST-NB builds passed with warnings treated as errors, and HTML checks verified all three tables. Only four Markdown cells changed; notebook code, outputs, and metadata are preserved. The full test suite and full documentation site build were not run; nbval-lax does not compare saved outputs.

Original issue: #1229
