+Pluma docs (Astro)
+
+Local development
+
+Prerequisites:
+- Node 18+ and pnpm
+
+Commands (from repo root):
+
+```bash
+pnpm install
+pnpm --filter ./docs dev     # run dev server
+pnpm --filter ./docs build   # build static site and generate public/search-index.json
+pnpm --filter ./docs preview # preview build
+```
+
+Rebuilding the search index
+
+The build step runs docs/scripts/build-search-index.mjs which scans docs/src/pages and outputs public/search-index.json.
+To rebuild manually:
+
+```bash
+cd docs
+node ./scripts/build-search-index.mjs
+```
+
+Search
+
+Search is client-side using FlexSearch and public/search-index.json. No external services are required. Algolia can be integrated later by providing keys and toggling the client.
+
+Artifacts
+
+Build log and screenshots are saved in docs/artifacts/ for QA.
+
+Known limitations
+
+- The search index is generated from markdown/astro page content at build time. Large sites will increase index size.
+- Theme toggle is a simple attribute toggle for demo; persistent preference storage can be added.
