+# Accordion — Component Spec
+
+## Purpose
+
+A vertically stacked set of disclosure items: each item has a clickable header that expands or collapses its content panel. Use it to condense long content into scannable sections. Unlike `tab-view` (mutually-exclusive panels shown in place), an accordion can keep one item open at a time (`type="single"`) or several at once (`type="multiple"`), and its content expands inline below each header.
+
+## Usage
+
+```vue
+<script setup>
+import Accordion from '@aziontech/webkit/accordion'
+</script>
+
+<template>
+  <Accordion
+    type="single"
+    collapsible
+    default-value="overview"
+    size="medium"
+    arrow-position="right"
+  >
+    <Accordion.Item value="overview">
+      <Accordion.Trigger>What is Azion?</Accordion.Trigger>
+      <Accordion.Content>Azion runs your code at the edge, close to users.</Accordion.Content>
+    </Accordion.Item>
+    <Accordion.Item value="pricing">
+      <Accordion.Trigger>How does pricing work?</Accordion.Trigger>
+      <Accordion.Content>Pay only for what you use, with no upfront cost.</Accordion.Content>
+    </Accordion.Item>
+    <Accordion.Item value="support" disabled>
+      <Accordion.Trigger>Enterprise support</Accordion.Trigger>
+      <Accordion.Content>Available on Business and Enterprise plans.</Accordion.Content>
+    </Accordion.Item>
+  </Accordion>
+</template>
+```
+
+Tree-shaking alternative — the same sub-components as standalone imports:
+
+```vue
+<script setup>
+import Accordion from '@aziontech/webkit/accordion'
+import AccordionItem from '@aziontech/webkit/accordion-item'
+import AccordionTrigger from '@aziontech/webkit/accordion-trigger'
+import AccordionContent from '@aziontech/webkit/accordion-content'
+</script>
+```
+
+## Sub-components
+
+The root ships a **compound API**: an `index.ts` (beside `accordion.vue`) attaches every sub-component to the root so `<Accordion.Item>` / `<Accordion.Trigger>` / `<Accordion.Content>` resolve from one import; the standalone imports above remain the tree-shaking path. The root is a disclosure component with `data-state="open|closed"`, so `Trigger` / `Content` are the correct anatomy names. Shared open-state flows through `provide`/`inject` (`injection-key.ts`), so the consumer wires nothing.
+
+- `accordion-item/accordion-item.vue` — One disclosure row. Registers itself with the root by `value`, derives its own open/closed state from the injected context, and groups a `Trigger` + a `Content`.
+  - Props: `value: string` (**required** — unique identifier used by the open-state model), `disabled?: boolean` (default `false` — prevents this item from toggling; from the Figma component description).
+  - Slot: `default` — the item's `Accordion.Trigger` and `Accordion.Content`.
+- `accordion-trigger/accordion-trigger.vue` — The clickable header row (Figma "Header"): renders the title plus the `pi pi-chevron-down` glyph, toggles the item through the injected context, and exposes `aria-expanded` / `aria-controls`. To satisfy the ARIA accordion pattern, the `<button>` is wrapped in a heading element.
+  - Props: `level?: 2 | 3 | 4 | 5 | 6` (default `3` — heading level of the wrapping `<h{level}>` for correct document outline).
+  - Slot: `default` — header title content.
+- `accordion-content/accordion-content.vue` — The collapsible panel. Mounts only when its item is open, reads the content/trigger ids from context, and exposes `role="region"` + `aria-labelledby`. The container applies no padding — the slotted content owns its own spacing.
+  - Slot: `default` — panel body content.
+
+Resulting layout (no per-component `package.json` — dropped repo-wide; the root `packages/webkit/package.json#exports` resolves every path; `.d.ts` is generated at publish time, never committed):
+
+```
+packages/webkit/src/components/content/accordion/
+├── accordion.vue                 (root; owns type/value/size/arrowPosition, provides context)
+├── index.ts                      (compound: attaches Item / Trigger / Content to the root)
+├── injection-key.ts              (shared AccordionContext)
+├── accordion-item/
+│   └── accordion-item.vue
+├── accordion-trigger/
+│   └── accordion-trigger.vue
+└── accordion-content/
+    └── accordion-content.vue
+```
+
+Exports to add to `packages/webkit/package.json#exports` (flat public names; category lives in the folder only):
+
+```jsonc
+"./accordion": "./src/components/content/accordion/index.ts",
+"./accordion-item": "./src/components/content/accordion/accordion-item/accordion-item.vue",
+"./accordion-trigger": "./src/components/content/accordion/accordion-trigger/accordion-trigger.vue",
+"./accordion-content": "./src/components/content/accordion/accordion-content/accordion-content.vue"
+```
+
+## Props
+
+Props below belong to the root `Accordion`. Sub-component props are documented in the **Sub-components** section above.
+
+| Prop | Type | Default | Required | JSDoc |
+|---|---|---|---|---|
+| `type` | `'single' \| 'multiple'` | `'single'` | no | Whether one or multiple items can be open at the same time. |
+| `value` | `string \| string[] \| null` | `undefined` | no | Controlled open item(s): a single `value` string in single mode, an array of values in multiple mode. Use with `v-model:value`. |
+| `defaultValue` | `string \| string[] \| null` | `null` | no | Initial open item(s) when uncontrolled. |
+| `collapsible` | `boolean` | `true` | no | In single mode, lets the open item collapse so that no item is open. |
+| `size` | `'medium' \| 'large'` | `'medium'` | no | Size token; affects header height, padding, and typography. Provided to every item via context. |
+| `arrowPosition` | `'left' \| 'right'` | `'right'` | no | Side of the header the chevron sits on. Provided to every item via context. |
+
+## Events
+
+Events below are emitted by the root `Accordion`.
+
+| Event | Payload | Notes |
+|---|---|---|
+| `update:value` | `string \| string[] \| null` | `v-model:value`. Fires when the open item(s) change. |
+| `value-change` | `string \| string[] \| null` | Convenience event mirroring `update:value`. |
+
+## Slots
+
+| Slot | Scope | Notes |
+|---|---|---|
+| `default` | — | The `Accordion.Item` children. Each sub-component's own `default` slot is documented in the Sub-components section. |
+
+## States
+
+- Visual states: `default`, `hover`, `focus-visible`, `active`, `disabled`
+- `data-state` values: `open` | `closed` — on the item, the trigger, and the content
+- `data-disabled` mirrors the per-item `disabled` prop
+- `data-orientation`: `vertical`
+
+## Motion & Animations
+
+| Trigger | Animation / Transition | Token (see `.claude/docs/DESIGN.md` § Animations) | Reduced-motion fallback |
+|---|---|---|---|
+| chevron rotate on open | `transition-transform duration-150 ease-out` + `data-[state=open]:rotate-180` | inline (matches catalog) | `motion-reduce:transition-none` |
+| content reveal on open (on `Accordion.Content` only) | fade-in semantic utility from `animations.js` | semantic (matches catalog) | reduced-motion fallback via the matching `motion-reduce` utility |
+| header hover state change | `transition-colors duration-150 ease-out` | inline (matches catalog) | `motion-reduce:transition-none` |
+
+> Figma declares no motion spec for this component (the open/closed/hover states are static variants). The transitions above are taken from our existing catalog — the chevron pattern mirrors `select-trigger.vue` (`data-[state=open]:rotate-180`), and the content reveal reuses the fade-in semantic utility (as `tab-view` does). No component-local `@keyframes`.
+
+## Tokens
+
+| Region | Token (DESIGN.md) |
+|---|---|
+| header title typography (large / medium) | `.text-body-md` / `.text-body-sm` |
+| content body typography (large / medium) | `.text-body-sm` / `.text-body-xs` |
+| header title text | `var(--text-default)` |
+| content body text | `var(--text-muted)` |
+| disabled text | `var(--text-disabled)` |
+| header divider (bottom border) | `var(--border-default)` |
+| item divider when closed | `var(--border-muted)` |
+| header padding-x | `var(--spacing-md)` |
+| header gap (arrow right / left) | `var(--spacing-sm)` / `var(--spacing-xs)` |
+| focus ring / ring offset | `var(--ring-color)` / `var(--bg-canvas)` |
+
+## Theme gaps
+
+| Figma variable | Temporary primitive | Follow-up |
+|---|---|---|
+| `Heading/xss` · `Heading/xs` (Sora Regular, line-height 1.4) used for the header title | `.text-body-sm` · `.text-body-md` (line-height 1.5, same 14px / 16px sizes, same Regular weight) | `TODO: decide whether to surface text-heading-xs/xxs in DESIGN.md, or keep the body family for the title` |
+| `Hover=True` variant (delta not resolvable via the Figma MCP bound-variable API) | `hover:bg-[var(--bg-hover)]` on the trigger | `TODO: confirm the header hover treatment with design` |
+| `--border-width-default` (0.8px header / item divider) | `border-b` (1px) | `TODO: tokenize the sub-pixel border width if it must match exactly` |
+
+## Accessibility (WCAG 2.1 AA)
+
+- Visible focus (Figma has no focus variant; we own it): `focus-visible:ring-2 focus-visible:ring-[var(--ring-color)] focus-visible:ring-offset-2 focus-visible:ring-offset-[var(--bg-canvas)]` on each `Accordion.Trigger`.
+- Keyboard map: `Tab` / `Shift+Tab` move between triggers and into open content; `Enter` / `Space` toggle the focused item; `Arrow Down` / `Arrow Up` move focus to the next / previous trigger; `Home` / `End` move focus to the first / last trigger.
+- ARIA: each trigger is a `<button>` with `aria-expanded` reflecting open state and `aria-controls` referencing its content; the trigger button is wrapped in a heading element (`<h{level}>`, default `h3`); the content panel has `role="region"` and `aria-labelledby` referencing its trigger. A `disabled` item sets `disabled` + `aria-disabled` on its trigger.
+- Contrast ≥4.5:1 for text (title `--text-default`, body `--text-muted` on the surface) / ≥3:1 for the chevron glyph, including the disabled state (`--text-disabled`).
+- `motion-reduce:transition-none motion-reduce:animate-none` on the chevron rotation and content reveal.
+- Touch target: the `large` header is 40px tall and the full-width header row is the hit area (≥40×40). The `medium` header is 32px tall — a justified deviation matching the Figma `medium` size token, mitigated by the full-width clickable row.
+
+## Stories (Storybook)
+
+- **Default** — a single-mode accordion with a few items, one open via `default-value`.
+- **Sizes** — composite story rendering `medium` and `large` side by side.
+- **ArrowPosition** — composite story rendering `right` and `left` chevron placement side by side. _Justification:_ `arrowPosition` is a visual variant axis taken straight from the Figma variant matrix, exactly like `size`; the canonical one-composite-story-per-axis pattern applies.
+- **Disabled** — an accordion whose middle item carries the per-item `disabled` prop, demonstrating the non-toggling state.
+- **Multiple** — an accordion with `type="multiple"` and two items open at once. _Justification:_ single-vs-multiple is the component's core behavioral contract (called out in the Figma component description) and is the one mode the single-mode Default story cannot show.
+
+## Constraints — DO NOT
+
+<!-- This block is injected VERBATIM into every sub-agent prompt.
+     spec-validator rejects the spec if this block is missing or shorter than the template. -->
+
+- Do not add props beyond the Props table above. If you need a prop that is not listed, emit `BLOCKED: missing prop <name>` and stop — do not invent.
+- Do not add events beyond the Events table above. Same rule for slots and sub-components.
+- Do not invent imports. Every `@aziontech/webkit/*` path must exist in `packages/webkit/package.json#exports`. Every relative import must resolve to a real file. Every npm package must be installed.
+- Do not use HEX/RGB/HSL colors, Tailwind palette names (e.g. `bg-blue-500`), raw typography classes (e.g. `text-sm`), `any`, `@ts-ignore`, or `class` inside `defineProps`.
+- Do not install or import positioning/animation libraries (`@floating-ui/*`, `popper.js`, `tippy.js`, `gsap`, `framer-motion`, `motion`, `@vueuse/motion`, `@formkit/auto-animate`, drag-drop runtimes, scroll virtualization libs). Use CSS + Vue primitives (`<Teleport>`, `<Transition>`). See `.claude/rules/dependencies.md`.
+- Do not improvise animations. Every `animate-*` / `transition-*` class must come from `packages/theme/src/tokens/semantic/animations.js`; every motion-bearing class pairs with `motion-reduce:*` on the same class string; no component-local `@keyframes`.
+- Do not create class presets in JavaScript (`const kindClasses = {...}`, `const sharedClasses = [...]`, `const sizeClasses = {...}`, `const rootClasses = computed(...)`). Variants live on `data-*` attributes consumed by Tailwind `data-[attr=value]:`. All utilities live inline on the root element's `class` attribute. No `<style>` block, no component-local `.css`/`.scss`. See `.claude/rules/styling.md`.
+- Do not inherit artifacts as-is from another design system, Figma file, library, or pre-existing `CONTRACT.md` / `README.md`. Rewrite to our conventions. See `.claude/rules/migration.md`.
+- Do not add Figma references to Storybook stories. No `parameters.design`, no `parameters.figma`, no Figma URLs in `docs.description.*`, no `@storybook/addon-designs` import. The Figma link is owned by `<name>.figma.ts` (Code Connect). See `.claude/docs/COMPONENT_REQUIREMENTS.md`.
+- Do not use `parameters.actions.argTypesRegex` (deprecated in Storybook 8 and silently misroutes Vue 3 emits) or `parameters.actions.handles` (DOM-only). Declare every event explicitly in `argTypes` with a camelCase `on<Event>` key and `{ action: '<emitted-name>' }`. Do not use the legacy CSF2 `Name.args = {...}` form — always object-style CSF3.
+- Do not add bespoke Storybook stories beyond Default + Types + Sizes + state stories (`Loading`, `Disabled`) for the props the component actually declares, unless the spec's "Stories (Storybook)" section explicitly justifies the addition. Do not split Types/Sizes into one-story-per-variant — the composite stories are the canonical pattern.
+- Do not duplicate the `## Usage` block from the spec inside the Storybook story body. The block is injected once into `parameters.docs.description.component` by the storybook-write skill; copy it nowhere else.
+- Do not edit `.claude/docs/DESIGN.md`, `.claude/docs/COMPONENT_REQUIREMENTS.md`, or `.claude/docs/PRIMEVUE_ABSTRACTION.md`.
+- Do not edit the root `package.json` or `.github/workflows/*`.
+- Do not export composition sub-components without attaching them to the root compound (`index.ts` via `Object.assign`; vue-tsc generates `index.d.ts` — never hand-write it); the root export and the root `package.json` main/module point at `index.ts`, `types` at `index.d.ts`. Do not invent overlay part names (`Trigger` / `Content`) on a component with no `data-state=open|closed`, and do not collapse a slot-shaped concern into a config-array prop. See `.claude/rules/compound-api.md`.
+- Do not change `structure` after `status: approved`. To change structure, bump `spec_version` and re-author the spec.
+- Do not create files outside the paths declared by your task (the orchestrator tells you exactly which files to write).
+- Do not run `git` commands, `pnpm install`, or any command that changes the lockfile.
+- If anything in the spec is ambiguous or contradicts the rules, emit `BLOCKED: <one-sentence reason>` and write nothing.
