name: kortix-design-system description: "Kortix brand + design system: the rules, tokens, and component library for building any Kortix frontend UI (apps/web). Load this WHENEVER you create or edit a page, screen, component, list, card, badge, avatar, modal, form, empty state, or any visual surface in apps/web — and whenever deciding whether to reuse an existing component or add a new one. Enforces: always import from the design system, never hand-roll chrome, people-are-round / things-are-square avatars, and one standardized brand identity. Source of truth is globals.css + the live /design-system page + src/components/ui."

Kortix Design System

The single reference for building Kortix UI. If you are touching a visual surface in apps/web, follow this. The goal is one standardized, simple, recognizable brand identity — achieved by always composing the design system instead of hand-rolling.

Philosophy

Simplicity is the brand. Black & white + one accent color. Calm, dense, legible. No decoration that doesn't carry information.
The design system is the source of truth. Everything imports from @/components/ui/* and the tokens in globals.css. A screen should read like a sentence built from shared words.
AI-native & self-documenting. The living styleguide at /design-system (apps/web/src/app/(home)/design-system/page.tsx) renders every component. When you add a component, you add it there too — so the system can never drift from its documentation.

The one rule that matters

Reuse > Compose > Create. In that order. Never hand-roll something the system already provides.

Decision flow when you need a UI piece:

Reuse — does a component in src/components/ui/ already do this? Use it. (Check the list below and the /design-system page first.)
Compose — can you build it from existing primitives + tokens? Do that (this is how SectionCard is just Card + a header).
Create — only if 1 and 2 fail. Then:
- Put it in src/components/ui/<name>.tsx, built from tokens and existing primitives.
- Keep the API tiny and prop-driven; match the conventions of neighboring files.
- Add a showcase block to /design-system (a nav entry in TOC_SECTIONS + a <div id="pat-…"> block with ComponentLabel/ComponentDesc/DemoContainer). If it's not on the page, it doesn't exist.

Tokens — `globals.css` is law

For apps/web, apps/web/src/app/globals.css is the implementation source of truth for color, typography, radius, spacing, shadows, borders, and motion. brand-guidelines explains the brand intent (neutral base, one accent per surface, Roobert, subtle shadows); if a value conflicts, globals.css wins. Use semantic Tailwind tokens, never raw hex/OKLCH/RGB values and never one-off arbitrary radii or font sizes.

Color tokens: use the implemented tokens exposed in @theme inline: background/foreground, card/card-foreground, popover/popover-foreground, primary/primary-foreground, secondary/secondary-foreground, muted/muted-foreground, accent/accent-foreground, destructive/destructive-foreground, border, input, ring, sidebar-*, chart-1…chart-5, and brand accents kortix-base, kortix-blue, kortix-yellow, kortix-orange, kortix-green, kortix-purple, kortix-red. In components, write classes like bg-background, text-foreground, bg-card, text-muted-foreground, border-border, ring-ring, bg-kortix-blue. Never use raw Tailwind palette classes (bg-blue-500, text-red-400, bg-green-600, border-amber-300, etc.), raw values (#fff, oklch(...), rgb(...)), or hardcoded theme hacks (bg-black/10, bg-white/10).
Accent discipline: the app is neutral first. Use one kortix-* accent per surface when content needs color; use chart-* only for data visualization. For normal app selection and activity, prefer primary tint (bg-primary/[0.05]–bg-primary/[0.10], text-primary, border-l-primary) over flat grey fills.
Red is the brake, not the paint. destructive/red is reserved for the single irreversible confirmation step — the primary button inside a ConfirmDialog/AlertDialog. Never color routine actions red: Log out, Cancel, Close, navigation, and every menu row (even Remove / Leave / Delete entries) stay neutral and only turn red at the final confirm. Red sprinkled on menus and links reads as noise and looks off — restraint is the brand.
A Danger Zone stays calm. SectionCard tone="destructive" is a neutral panel with only a faint warm hairline edge (border-destructive/25) — its title and description read normally (no red text, no red fill), and its trigger button is neutral (e.g. variant="outline") because it just opens a confirm. The single red lives on that final confirm button — never on the panel, the title, or the trigger. A panel painted red is the #1 thing that makes the product look aggressive; don't.
Selected / active = tinted primary, never flat grey. The brand is monochrome, so a flat grey fill used to mean "selected"/"active" reads as an accidental smudge. Active toggles, selected tabs, and "on" pills use variant="subtle" (bg-primary/10 text-primary), never variant="secondary" or bg-muted. Selected rows/cards use bg-primary/[0.05]–bg-primary/[0.08], optionally with border-l-2 border-l-primary. Dense command/menu rows use the primitive's data-[selected=true]:bg-foreground/[0.06]. Image scrims/overlays use bg-foreground/[0.06].
Typography: --font-sans maps to var(--font-roobert) and --font-mono maps to var(--font-roobert-mono). Use font-sans for UI, headings, and body; use font-mono only for code, paths, IDs, CLI/config nouns, and technical snippets. Fallbacks and CJK handling live in globals.css; do not override them per component.
Type scale: keep html at font-size: 100%; never simulate zoom by changing root size. Use named text tokens only: text-xs = metadata/captions/badges/timestamps; text-sm = dense UI rows, menus, compact buttons, sidebar labels; text-base = readable body, form text, chat/content; text-lg through text-8xl = page hierarchy, marketing, and display. Section titles are text-base font-semibold; row titles are text-sm font-medium unless content-heavy, then text-base.
Typography details: globals.css defines line-height tokens for every text size, --tracking-normal: 0em, antialiasing, text-rendering: optimizeLegibility, and Roobert feature settings (ss10, ss09, ss03, ss04, ss14, palt). Do not loosen body tracking or add arbitrary type utilities like text-[10px], text-[13.5px], or text-[0.875em]. Syntax/color utilities such as text-[var(--shiki-dark)] are allowed because they are colors, not font sizes.
Navigation hierarchy: Parent/child rows stay on the same readable title size (text-sm in dense sidebars). Show hierarchy with indentation, a border, a dot/icon, opacity, or metadata treatment — not by shrinking child titles below the parent.
Radius: use only the implemented radius tokens from globals.css (rounded-sm, rounded-md, rounded-lg, rounded-xl, rounded-2xl) plus rounded-md. App chrome convention: main containers, cards, panels, dialogs, inputs, textareas, selects, popovers, dropdown/context menus, command palettes, tables, banners, alerts, and selectable option cards use rounded-2xl. Pills (buttons, badges) use rounded-full. Menu/list highlight rows use rounded-lg; tiny micro-bits (kbd keys, swatches, ≤24px icon squares) may use the smaller token that matches the primitive. Never use arbitrary radii like rounded-[5px].
Form controls: Input, Textarea, Select share ONE treatment — bg-card, border, rounded-2xl, accent focus ring (focus:ring-2 focus:ring-primary/50), no shadow. Input is canonical; the other two mirror it. Never restyle a field per-usage (no per-field bg-transparent, shadow-xs, or a custom/neutral focus ring).
Spacing and borders: use Tailwind spacing utilities backed by --spacing: 0.23rem; use --spacing-sidebar and desktop/titlebar inset variables only in shell chrome. Border color comes from border-border; border thickness follows the design-system components and the --border-width token where a primitive uses it. Do not invent heavier strokes.
Shadows: shadows exist but stay subtle. Use the implemented shadow-2xs…shadow-2xl tokens only when elevation is needed; most controls and dense app surfaces should remain flat. Never add glow, neon, colored shadows, or custom box-shadow values.
Motion: use duration/easing tokens from globals.css: duration-fast 100ms, duration-normal 150ms, duration-moderate 200ms, duration-slow 300ms, duration-slower 500ms; ease-default, ease-in, ease-out, ease-in-out. Default UI transitions are 150–200ms with ease-default or ease-out; repeated keyboard-driven actions should not animate.

Component catalog — what to use when

Surfaces & layout

SectionCard — THE panel. Composes Card (rounded-2xl) + a divided header (title, muted count, description, trailing action). flush seats a List edge-to-edge; tone="destructive" is the danger zone (a calm neutral panel with a faint warm edge — not a red box). Use this instead of any <section className="rounded-xl border …">.
Card / CardHeader / CardContent — raw surface when SectionCard is too opinionated.
Section — labelled, boxless grouping inside a PageShell (uppercase micro-label + whitespace).
PageShell / PageHeader — page width + intro.

Lists & rows

List + ListRow — THE list. ListRow has a leading slot (avatar/icon), title + inline badges, a subtitle (use InlineMeta), and a trailing slot (status badge + kebab). A clickable row is an accessible div role="button" so it can still hold a trailing menu (wrap that menu in stopPropagation). Use this instead of hand-rolled <ul className="divide-y">.
Table / DataTable — only for genuinely multi-column tabular data. Lists beat tables for entity rows.
DefinitionList / DefinitionRow — key/value detail panels.

Identity

UserAvatar — a person (round). Renders the supabase profile picture when present (avatar_url/picture, referrerPolicy="no-referrer"), else neutral monochrome initials — no colored backgrounds. People and things share the same neutral material and size scale; only the shape differs. Pending invites are people too → UserAvatar by email.
EntityAvatar — a thing: account, project, group, workspace (rounded square; initial or Lucide icon). People are round, things are square — never mix. Both share the xs|sm|md|lg|xl scale so they align.

Atoms

Badge — status chips. Use variant (outline|secondary|destructive|success|…) + size="sm" for dense UI. Never hand-roll h-4 rounded-md px-1 text-[9px].
Button — pill (rounded-md) by default. Sizes sm|default|lg|icon. Variants default|outline|ghost|destructive|secondary|subtle.
InlineMeta — the a · b · c fact strip (skips falsy children). Use for row subtitles & header meta instead of manual ·// separators.
InfoBanner — inline status / note box (manifest status, warnings, tips, the live diff preview). tone = neutral|info|success|warning|destructive + optional icon, title, action. Use this instead of hand-rolling rounded-md border border-amber-500/30 bg-amber-500/5 colored one-offs. (Alert is the heavier, role-flagged full-width variant.)
EmptyState — zero-state: icon + title + description + up to two actions. Use for every empty list.
Tabs (+ TabsListCompact) — pill tabs.
Skeleton — loading; match the shape it replaces (round vs rounded-lg).

Dos & Don'ts

✅ Panels → SectionCard. ❌ <section className="rounded-xl border border-border/70 bg-card"> with a hand-rolled header.
✅ Danger zones → <SectionCard tone="destructive">. ❌ a bespoke red box.
✅ Destructive intent → a neutral trigger (menu row / button) that opens a confirm; red appears only on that final confirm button. ❌ text-destructive on Log out, Cancel, links, or menu rows.
✅ People → UserAvatar with neutral initials / real photo. ❌ a colored avatar background or white-on-color initials.
✅ Lists → List + ListRow. ❌ ad-hoc <ul className="divide-y"> with custom <li> flex rows.
✅ Badges → <Badge size="sm" variant="…">. ❌ className="h-4 rounded-md px-1 text-[9px]".
✅ People → UserAvatar (round); things → EntityAvatar (square). ❌ a custom initial tile, or a circle for a project / a square for a person.
✅ Meta lines → InlineMeta. ❌ manual <span className="text-muted-foreground/40">·</span>.
✅ Empty views → EmptyState. ❌ centered <p> with custom padding.
✅ Status / note boxes → <InfoBanner tone="…">. ❌ <div className="rounded-md border border-amber-500/30 bg-amber-500/5 …"> colored one-offs.
✅ Form fields → bare Input/Textarea/Select (they already match). ❌ a per-field bg-transparent, shadow-xs, or custom focus ring that makes two fields look like different materials.
✅ Font sizes → named text tokens (text-xs, text-sm, text-base, text-lg+). ❌ arbitrary font-size classes like text-[11px], text-[13.5px], or text-[0.875em].
✅ Nested nav/session rows → same readable title token, with indentation/dot/border for hierarchy. ❌ child titles made smaller than parent titles.
✅ Color/radius via globals.css tokens (bg-muted, bg-kortix-blue, rounded-2xl). ❌ Tailwind palette colors (bg-blue-500, text-red-400, bg-green-600), raw values (#fff, oklch(…)), rounded-[5px], rounded-md/rounded-xl on a container.
✅ Selected/active → tinted primary (variant="subtle", bg-primary/[0.05], border-l-primary). ❌ a flat grey selected/active state (variant="secondary", bg-muted, hardcoded bg-black/10).
✅ Modals: header border-b, padded body, flush footer bar (flex items-center justify-end gap-2 border-t border-border/60 bg-muted/30 px-6 py-3). ❌ -mx-6/mt-4 hacks or leftover bottom padding under the footer.
✅ One shared component imported everywhere. ❌ a second copy of an existing component (e.g. a local CreateAccountModal).

Modal pattern (canonical)

<DialogContent className="gap-0 overflow-hidden p-0 sm:max-w-md">
  <DialogHeader className="border-b border-border/60 px-6 pt-6 pb-4"> … </DialogHeader>
  <form onSubmit={…}>
    <div className="space-y-4 px-6 py-5"> {/* fields */} </div>
    <div className="flex items-center justify-end gap-2 border-t border-border/60 bg-muted/30 px-6 py-3">
      <Button variant="ghost">Cancel</Button>
      <Button type="submit">Confirm</Button>
    </div>
  </form>
</DialogContent>

Workflow checklist

Open /design-system (run the app, see kortix-design-system/run skills) and skim src/components/ui/ before writing UI.
Build the screen by composing primitives — SectionCard + List/ListRow + UserAvatar/EntityAvatar + Badge + InlineMeta + EmptyState.
If you must create a primitive: build it from tokens, keep it tiny, and add a showcase block to /design-system.
Verify: no hardcoded colors/radii, no hand-rolled chrome, correct avatar shapes, themes still work, tsc clean for the files you touched.

The reference implementation that follows all of the above: the account screens (src/app/accounts/**) and the IAM components (src/components/iam/**).
