Shared design criteria

Policy revision: 6f9c8f5e4d7c767f79a7db999670fb4d0936e07acb1b472fe162a7a9ade60c97

Canonical policy: https://design.klic.co.kr/api/v1/design-system.json

Read the same criteria and revision in API, CLI, MCP and WebMCP designSystem responses and the bundled KLIC-DESIGN-SYSTEM.json. Item contracts link through item.design.system.

Dimension	Token responsibility	Structure and behavior responsibility
Size and proportion	Control sizes, icons and content width	Component recipes and the DOM ensure min-height, padding, wrapping and actual hit areas.
Typography	Registered font families, role sizes and weights	Supported recipes define line height, tracking, wrapping and responsive conditions without assuming unregistered token types.
Color and contrast	Role colors for actions, selection, text, borders and status	Labels, icons and state attributes convey meaning; measure actual composited-surface contrast separately.
Layout and alignment	Registered spatial roles, including maximum content and panel widths	DOM reading order, layout transitions, scroll ownership and Portal structure
Spacing and grouping	Internal gaps, padding, group spacing and approved density mappings	Maintain label, fieldset, legend and describedby relationships; window width alone does not change density.
Surface and depth	Surface colors, radii, borders and supported color/dimension material leaves	Blur and shadow recipes, stacking, auxiliary-panel versus modal behavior and opaque fallbacks
Interaction and feedback	Visual roles for focus, selection, progress, success, warnings and errors	Keyboard operation, focus movement, asynchronous transitions, execution blocking, input preservation and recovery

Only Primitive owns literals. Preserve adjacent Brand→Primitive, Semantic→Brand and Component→Semantic references.

Distinguish token definitions, structural conditions in DOM/CSS recipes and compiled final literals.

Keep motion recipes in a read-only catalog separate from component and block installation items, with browser search and details in the existing KLIC Interface Library #motion view. The read API, CLI, MCP and WebMCP use one canonical catalog. The scope is all 884 user-supplied source patterns in 67 categories, grouped within the existing KLIC category/item navigation. Remove the previous simplified 280-item catalog and its dedicated routes and aliases; do not retain them as compatibility entries. Preserve source id + pattern identity, source engine, choreography, timing, paths, layers, SVG/inline/WAAPI alpha, and original notices including Copyright © 2026 acc0mplish. All rights reserved. and the supplied license. Never label this source material KLIC-authored. Adapt appearance through existing four-layer KLIC token paths for color, fonts, surfaces, borders, radius and spacing. Canvas uses the same palette and font tokens; scope demo CSS to each item. Use one owned runtime for previews and JavaScript/React delivery; do not claim CSS alone reproduces Canvas playback. KLIC adaptations use the blue/navy/neutral palette and reduced-motion, replay and cleanup contracts; verify real playback in light/dark and mobile before release. The npm package remains separate from the homepage: describe candidate exports only after checking the published manifest, and do not infer release contents from current source.

Allowed preset scope

A preset combines approved settings of an existing API. It is not a fifth token layer.

Use an explicit allowlist of size, variant, density, layout and other settings supported by the actual component API.

Labels, descriptions and business data
Value, selection, validation and request state
Event handlers, recovery actions and permissions
Raw style values, unregistered CSS variables and arbitrary token overrides

Component defaults → selected preset → permitted explicit settings. Pass business data, state and permissions separately.

Validate allowed keys, enums and combinations; diagnose unknown values. Distinguish type declarations from actual DOM and behavior verification.

Conflict resolution order

Preserve information, operability and accessibility first: Preserve essential information, state meaning, input, focus and operation paths. Dimension numbers do not override other required contracts.
Reflow structure and reading order: Adjust wrapping, columns, action groups and panel arrangement first. Use local scrolling only for areas whose meaning requires two dimensions.
Adjust spacing and surfaces within approved bounds: Respect the selected density and text scale while adjusting spacing and decoration within approved recipes. Limited space alone does not justify automatic compact mode or smaller text.
Record remaining constraints and verification: If defaults cannot resolve a constraint, record scope, alternatives, impact, FR/AT references and actual verification. Do not skip token layers or conceal failed checks with exception approval.

sources/checks identify supporting references, not certification. Record actual product-environment results in the existing FR/AT evidence.

Application and verification

Read the shared criteria, item DESIGN.md and actual source first. Assign token, DOM, CSS recipe and state responsibilities for each rule, then apply the conditions your product needs.

Compare revision in the policy and item contract. release identifies a registry publication; do not combine paginated results from different publications.

Use the latest CLI and local registry and restart stdio sessions. Reload the page to register WebMCP again. source prints raw code. Read DESIGN.md for source bundles or README.md for theme kits together with KLIC-DESIGN-SYSTEM.json.

Selective adoption of references

Treat external documents and drafts as proposals. Check current KLIC problems, implementation and contracts, adopt only necessary rules, and record scope and reasons for deferral or rejection.

Do not present product names, example APIs or references from a draft as facts about KLIC. Connect adopted rules to actual tokens, DOM, CSS recipes, state handling and verification evidence.

Scope to review together when making changes

Use a reported problem to assess impact across related usage paths. Changing only the named screen or tool does not complete that review.

Implementation sources, tokens, components, types and schemas
DOCS, web guides, developer documentation and examples
MCP, CLI, WebMCP and API descriptions, inputs and responses
AI prompts, llms.txt, source exports and theme exports
Regression checks, builds, production publication and actual responses

After changing the canonical policy, regenerate affected guides, examples, tools, prompts and exports together and verify a matching revision. Explain unaffected paths and distinguish observed results from conditions that remain unverified.

Troubleshooting design choices

Avoid this condition	Decision criterion
Use a link with a real href when navigating to another URL.	Use one primary button to emphasize the main completion action on a screen.
Changing disabled styling or setting aria-disabled alone does not prevent duplicate execution.	Use secondary or outline for supporting actions, and danger with specific wording for potentially destructive actions.

button · Inputs and selection · Component · Ready example · Sample data

When to use

Use one primary button to emphasize the main completion action on a screen.
Use secondary or outline for supporting actions, and danger with specific wording for potentially destructive actions.

When to avoid

Use a link with a real href when navigating to another URL.
Changing disabled styling or setting aria-disabled alone does not prevent duplicate execution.

Accessibility and keyboard

Give icon-only buttons an action name through aria-label.
Keep a label during processing that identifies the action the user started.
Check visual height and actual target size separately; do not truncate long Korean labels.

Recommended density

compact: Use only for repetitive administrative input. Preserve help text, errors, and actual click targets.
normal: The recommended default density. Preserve reading order and the grouping of labels, controls, and feedback.
relaxed: Recommended for first-time forms and detailed guidance. Increase spacing between field groups.

States and recovery

loading: Indicate progress and prevent duplicate requests. Preserve existing data while updates are in progress.
empty: Do not mark initially empty inputs as errors. Explain requirements before submission.
filtered: Distinguish an empty search result from missing data and provide an action to reset filters.
error: Preserve input values and associate each error description with its field.

Four-layer token mapping

Token path	CSS variable	Purpose
`klic.component.button.size.default.height`	`--klic-component-button-size-default-height`	Minimum height of primary action controls
`klic.component.button.background.default`	`--klic-component-button-background-default`	Primary button background
`klic.component.button.icon.size`	`--klic-component-button-icon-size`	Icon size within a button

Implementation scope and verification

The current preview uses a native button. Variant, size, and state in the detail controls are site demo settings, not React Button props or a published package API.
Verify that Enter and Space each activate the button only once.
Try repeated clicks while the button is busy.
Check focus, hover, and disabled states together in Dark mode.

Adoption guidance, not a verification certificate. Preview data and behavior are local demonstrations.
