Individual skill

layout-grid

Grid and alignment rules for a macOS SwiftUI app, with three checks that catch misalignment (a lint for off-grid numbers, a layout probe that measures real frames in snapshot mode, and a grid overlay). Use when building or reviewing a custom page, card, row, form, or sheet, after every build that touched layout, or when the user says something looks misaligned, crooked, cramped, or unevenly spaced.

# Layout grid

Agents guess numbers. A guessed `.padding(13)` looks almost right and
makes the whole app feel slightly off. This skill replaces guessing with
one scale and three checks that fail when something is off.

The template has everything in place: `Sources/<App>/UI/Grid.swift` and
`tools/`. For an app made before this skill, copy `UI/Grid.swift`,
`tools/grid-lint.sh`, and `tools/check-layout.swift` from the `new-mac-app`
skill's template, and the layout file line from its `Snapshot.swift`.

## The rules

1. Every padding, spacing, and size comes from `Space`: `xs 4`, `sm 8`,
