# fc.page.section.column

Compatibility alias for `fc.column` used in page-section layout manifests.

## One-line Description
Defines a column container within page section layouts, using the same behavior as `fc.column`.

## When to Use
- Legacy manifests that reference `fc.page.section.column`
- Grid-based page sections where components are arranged by columns
- Backward-compatible layout migrations to canonical aliases

## Key Props
| Prop | Type | Required | Description |
|---|---|---|---|
| xs | number | No | Width on extra-small breakpoints |
| sm | number | No | Width on small breakpoints |
| md | number | No | Width on medium breakpoints |
| lg | number | No | Width on large breakpoints |
| xl | number | No | Width on extra-large breakpoints |
| className | string | No | Additional CSS classes |

## Data Binding
Primarily structural layout component; binds child components rather than business data fields.

## Descendants
Yes. Supports nested content components.

## Composition Patterns
- Commonly nested under `fc.page.section`.
- Use multiple columns to compose responsive cards, fields, and action clusters.
- Prefer `fc.column` for newly authored manifests.

## Gotchas
- Column widths should be coordinated across siblings to avoid overflow.
- Alias and canonical component are functionally equivalent.

## Validation Rules
- Breakpoint width props should be valid grid values for the active theme/system.

## Manifest Example
```json
{
  "component": "fc.page.section.column",
  "props": {
    "md": 6
  },
  "descendants": [
    {
      "component": "fc.card.attribute",
      "props": {
        "title": "Details"
      }
    }
  ]
}
```

## AI Parse Notes
- **Primary intent:** Declarative Mystique component definition for manifests.
- **Selection signals:** Match by `alias`, `category`, and required `Key Props`.
- **Assembly hints:** Combine with compatible parent/child components listed in `Composition Patterns`.
- **Safety checks:** Validate required props and data bindings before manifest generation.
