+# Supplier FAQ Accordion
+
+A searchable, deep-linkable FAQ accordion for the supplier profile, so buyers
+can quickly find answers about pricing, policy, and process without leaving
+the profile page.
+
+Component: [`<SupplierFaqAccordion>`](../../src/components/dashboard/supplier-faq-accordion.tsx)
+
+---
+
+## When to use
+
+Use `<SupplierFaqAccordion>` on any supplier-facing profile surface where a
+buyer needs self-serve answers before booking or messaging a supplier:
+
+- **Supplier profile page** — below the hero and trust stats, ahead of
+  reviews.
+- **Support / help drawers** — a scoped subset of entries filtered to a
+  single category (e.g. only `"Policy"` entries).
+
+---
+
+## Anatomy
+
+```
+┌──────────────────────────────────────────────────────────┐
+│ SUPPLIER PROFILE                                         │
+│ Frequently asked questions                                │

+│ │ What is the refund policy?                            │ │

+└──────────────────────────────────────────────────────────┘
+```
+
+- **Header**: `<PanelShell>` provides the *eyebrow*, *title*, and
+  *description* slots (skip via `bare` when embedding elsewhere).
+- **Search**: a labeled `role="searchbox"` input with a clear button once a
+  query is entered. Result count and matched-term highlighting update live.
+- **List**: one `<li>` per FAQ entry, each a WAI-ARIA disclosure — a
+  `<button>` header (`aria-expanded` / `aria-controls`) toggling a
+  `role="region"` panel (`aria-labelledby`).
+
+---
+
+## Component API
+
+### Props
+
+```ts
+interface SupplierFaqAccordionProps {
+  entries: readonly SupplierFaqEntry[];
+  title?: string;                 // default: "Frequently asked questions"
+  eyebrow?: string;                // default: "Supplier profile"
+  description?: string;
+  searchPlaceholder?: string;
+  idPrefix?: string;               // default: "faq-", used for deep-link anchors
+  initialDeepLinkId?: string;      // overrides the URL hash on mount
+  bare?: boolean;                  // hide PanelShell chrome
+  className?: string;
+}
+```
+
+### `SupplierFaqEntry`
+
+```ts
+type SupplierFaqEntry = {
+  id: string;          // stable slug, used for the deep-link anchor
+  question: string;
+  answer: string;
+  category?: string;   // e.g. "Pricing" | "Policy" | "Process"
+};
+```
+
+---
+
+## Search behavior
+
+- Matching is case-insensitive substring matching across `question`,
+  `answer`, and `category`.
+- Matched terms are wrapped in `<mark>` in both the question and the answer.
+  Highlighting is a visual aid only — the result-count text carries the same
+  information for anyone who can't perceive color/background differences.
+- An empty query shows every entry, collapsed to their prior open/closed
+  state.
+- No matches renders a `role="status"` empty state instead of the list.
+
+## Deep linking
+
+- On mount, the component reads `window.location.hash`, strips the
+  `idPrefix`, and — if it matches an entry id — expands that entry and
+  scrolls it into view (`scrollIntoView({ behavior: "smooth", block: "start" })`),
+  then moves focus to its header.
+- `initialDeepLinkId` overrides the hash for cases where the host page
+  already parsed the route (e.g. Next.js `searchParams`).
+- Toggling any entry updates the hash via `history.replaceState` (no new
+  history entry), so a buyer can copy the current URL to share a specific
+  answer.
+- An unknown/stale hash is ignored — every entry renders collapsed, no error.
+
+---
+
+## Accessibility (WCAG 2.1 AA)
+
+- Implements the [WAI-ARIA disclosure (accordion) pattern](https://www.w3.org/WAI/ARIA/apg/patterns/accordion/):
+  each header is a native `<button>` with `aria-expanded` and
+  `aria-controls`; each panel is `role="region"` with `aria-labelledby`
+  pointing back at its header.
+- Keyboard support across the visible (filtered) headers only:
+  - `Arrow Down` / `Arrow Up` — move focus to the next/previous header,
+    wrapping at the ends.
+  - `Home` / `End` — jump to the first/last visible header.
+- The search input has a visually-hidden `<label>` and
+  `aria-describedby` pointing at the live result-count text.
+- Result-count changes are announced via a polite live region
+  (`<LiveRegion>`), so screen reader users hear updates without needing to
+  re-read the input.
+- Collapsed panel content is not rendered into the DOM (rather than only
+  visually hidden), so assistive tech and in-page search never encounter
+  stale/duplicate answer text.
+- Color is never the only signal: highlighted terms also appear in the
+  announced/visible result count, and expand/collapse state is exposed via
+  `aria-expanded`, not just the chevron icon.
+
+---
+
+## Responsive & theming notes
+
+- Layout is a single-column list at all breakpoints; the search bar and
+  result count stack above it. No horizontal scrolling at any width.
+- Uses the existing dark surface tokens (`bg-slate-900/40`,
+  `border-white/10`) — no additional design tokens introduced.
+- `<mark>` uses `bg-amber-300/90` with dark text for contrast against both
+  the light-on-dark question text and the panel background.
+- Works under `dir="rtl"`: the chevron and layout use logical Tailwind
+  utilities (`gap`, flex) rather than hard-coded `left/right`, aside from the
+  search icon and clear button positions, which mirror automatically under
+  RTL because they use `left-*`/`right-*` relative to the input's own
+  `dir` inheritance from the document.
+
+---
+
+## Edge cases covered
+
+| Case | Behavior |
+| --- | --- |
+| Long answers | No truncation or max-height clipping; the panel grows with content. |
+| Empty search | Shows the full list, `"Showing all N questions"`. |
+| No matches | `role="status"` empty state, no accordion list rendered. |
+| Empty `entries` array | Same empty state, `"Showing all 0 questions"`. |
+| Unknown deep-link hash | Ignored; all entries render collapsed. |
+| Dark mode | No dark-mode-specific branch; component is dark-surface by default and unaffected by an ancestor `.dark` class. |
+| RTL | Renders and functions identically; verified via `document.dir = "rtl"`. |
+
+---
+
+## Testing
+
+See [`supplier-faq-accordion.test.tsx`](../../src/components/dashboard/supplier-faq-accordion.test.tsx)
+for the full suite (25 tests, 100% line/function coverage on the component),
+covering: disclosure semantics, keyboard navigation, search/filter/highlight,
+deep-linking (hash + prop), empty states, long content, and RTL/dark-mode
+rendering.

+ * SupplierFaqAccordion — searchable, deep-linkable FAQ accordion for supplier

+ *
+ * Accessibility (WCAG 2.1 AA):
+ *  - Each header is a real `<button>` with `aria-expanded` / `aria-controls`.
+ *  - Panels use `role="region"` + `aria-labelledby` pointing back at the header.
+ *  - Arrow Up/Down move focus between visible headers; Home/End jump to the
+ *    first/last visible header, matching the standard accordion keyboard model.
+ *  - The search input has a visible label (visually hidden) and the live
+ *    result count is announced via a polite live region.
+ *  - Matched-term `<mark>` highlighting keeps sufficient contrast in both
+ *    light and dark themes and never conveys meaning by color alone (the
+ *    result count text carries the same information).
