Layout Framework Skill

Core rules (always follow)

• Use MUI v7 Grid with the size prop (not xs/md props).
• Prefer Grid container for column layouts; use Stack for simple vertical rhythm.
• Avoid hardcoded widths/heights; use theme spacing and responsive values ({ xs, md }).
• Wrap major sections in Paper background={1} with p: { xs: 3, md: 5 } and borderRadius: 6 unless the surrounding layout already provides a card.
• Keep inputs aligned in a consistent grid (e.g., 12 / 6 / 3 / 3, 8 / 4, 6 / 6). No uneven, ad-hoc sizing.
• Use Container only for page-level width constraints. Inside cards, use Grid for structure.

When to read references

• For exact examples of Box/Container/Grid/Stack usage, read:
  • references/component-docs-map.md
  • references/layout-patterns.md

Default layout patterns

• Two-column forms: Grid container spacing={{ xs: 2, md: 3 }} with size={{ xs: 12, md: 6 }}.
• Primary + secondary field: size={{ xs: 12, md: 8 }} + size={{ xs: 12, md: 4 }}.
• Address block: street 12, city 6, state 3, zip 3.
• Section cards: each form block inside Paper background={1} with internal Grid or Stack.

Process checklist

1. Identify the page sections and their cards.
2. Decide row/column structure using Grid (avoid ad-hoc sx flex sizing).
3. Normalize spacing with spacing={{ xs: 2, md: 3 }} and p: { xs: 3, md: 5 }.
4. Verify that labels/inputs align across rows and breakpoints.
5. Remove any hardcoded widths or manual flex ratios unless they map to a grid size.
