+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Commands
+
+```bash
+npm run dev      # Start dev server (http://localhost:4321)
+npm run build    # Type-check (astro check) + production build
+npm run preview  # Preview the production build locally
+```
+
+There are no test or lint commands beyond `astro check` (run as part of `build`).
+
+## Architecture
+
+**Cozy Den** is the personal site for hiddenden.cafe. It's an Astro 4 project in `hybrid` output mode with a Node.js standalone adapter, which means most pages are statically generated at build time but API routes under `src/pages/api/` run as server-side handlers at runtime.
+
+### Key directories
+
+- `src/content/` — Astro Content Collections (blog, coffee, links, guestbook). Schemas and Zod validation live in `src/content/config.ts`. Blog posts support frontmatter fields for tags, categories, series, audio URLs, and featured-essay flags.
+- `src/pages/api/` — SSR API endpoints. `api/guestbook/submit.ts` handles guestbook POST submissions; `api/admin/` handles admin session auth.
+- `src/lib/` — All shared TypeScript utilities: `db.ts` (SQLite setup/schema), `auth.ts` (admin sessions), `guestbook.ts` (submission logic), `spam.ts` (honeypot + keyword pattern detection + input sanitization), `blog.ts`, `readingTime.ts`.
+- `src/layouts/BaseLayout.astro` — Root layout; defines all global CSS custom properties (Catppuccin Mocha palette, typography, spacing).
+- `src/components/` — Reusable `.astro` components (Card, Nav, Section, ServiceItem, SupportItem).
+
+### Database
+
+SQLite via `better-sqlite3`. Tables: `guestbook_entries` (moderated submissions), `admin_sessions` (expiring tokens), `rate_limit` (per-IP), `audit_log`. The schema is initialized in `src/lib/db.ts` on first run — no separate migration step.
+
+### Styling
+
+Vanilla CSS only — no Tailwind. All colour tokens are CSS variables on `:root` using the Catppuccin Mocha palette, with `prefers-color-scheme` overrides for light mode. Animations respect `prefers-reduced-motion`. Fonts are monospace (JetBrains Mono / Fira Code / SF Mono).
+
+### Deployment
+
+The site runs as a Docker container (standalone Node on port 3000) behind Nginx. The image is pushed to `git.hiddenden.cafe`. Copy `.env.example` to `.env` for TTS API keys (Google / Mistral / OpenAI) used by `scripts/tts_generate.py` when generating audio versions of blog posts.
