Visual Consistency

A detector and fixer for the visual and layout consistency defects that show up in rendered UI: the systematic raggedness an AI generator emits and a senior notices at a glance. It finds where repeated elements that should line up do not, where spacing is arbitrary instead of systematic, and where variable-length content breaks a clean layout, explains the cost of each, and proposes a concrete CSS fix with a source. The full catalog with detection signals, fixes, exceptions, severity, and sources is in catalog.md; copy-pasteable recipes for the flagship cases are in recipes.md. Read the catalog before a scan.

It defers two neighboring concerns to sibling skills so it does not duplicate them: color literals and contrast to theme-colors, and component, hook, and TypeScript code smells to react-stinky. The accessibility line splits the same way: this skill owns the visual and sizing side (target size, focus-ring consistency, reflow, text spacing the user can override), react-stinky owns the semantic-markup side (roles, labels, keyboard handlers). Whether a screen should exist at all is ask-ux, upstream of everything here. If a sibling is not installed, note the finding in one line and move on.

The four it was built for

These are the defects that prompted the skill. Each has a clean, modern fix; the rest of the catalog generalizes them.

1. Uneven card heights in a grid. Cards in a row render at different heights because text length differs, so the grid looks busy. Grid and flex already stretch a row to its tallest card; the work is making the card a flex or grid column so its own footer pins to the bottom. See recipes.md.
2. Sibling cards whose sections do not line up. Same template, but each card's title, body, and footer start at a different Y, so nothing scans across the row. The modern answer is CSS subgrid: declare the row tracks once on the grid and let each card inherit them, so the tallest title sets the title row for every card. See recipes.md.
3. Trailing icons at ragged X positions. A list of links with an open-in-new-tab icon places the icon at a different X on every row because link text varies. Pin it with a two-column grid (1fr auto), or margin-inline-start: auto in a flex row, and add min-width: 0 so long text truncates instead of shoving the icon. See recipes.md.
4. Arbitrary, inconsistent spacing. Spacing falls back to off-scale magic numbers (13px, 7px, 22px), or mixes margin and gap, or pads similar containers differently. Snap every value to a spacing scale (4 and 8 point) referenced as a token, and prefer one gap on the parent over per-element margins. See recipes.md.
