+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Commands
+
+```bash
+bun run dev          # local dev server
+bun run build        # Next.js build
+bun run preview      # OpenNext Cloudflare build + local preview
+bun run deploy       # OpenNext Cloudflare build + deploy to Workers
+bun run prepare      # regenerate PandaCSS styled-system/ (run after panda.config.ts changes)
+bun run cf-typegen   # regenerate cloudflare-env.d.ts bindings
+```
+
+No test suite is configured.
+
+## Environment
+
+Copy `.env.local.example` to `.env.local` and set:
+
+```
+CMS_API_KEY=<microCMS API key>
+```
+
+The microCMS service domain is hard-coded as `nknighta-github` in `src/utils/cms.ts`.
+
+## Architecture
+
+**Stack**: Next.js 16 (Pages Router) · React 19 · TypeScript · PandaCSS · microCMS · GSAP · Framer Motion · deployed to **Cloudflare Workers** via `@opennextjs/cloudflare`.
+
+### Styling — PandaCSS
+
+All styles use the `css()` utility imported from `../../styled-system/css` (a codegen artifact). This is **not** Tailwind. The `styled-system/` directory is generated — never edit it by hand; run `bun run prepare` to regenerate after config changes.
+
+### CMS — microCMS
+
+`src/utils/cms.ts` exports a singleton client and typed helpers (`getBlogs`, `getBlog`, `getCategories`). Content endpoints used across the site:
+
+| Endpoint | Used by |
+|---|---|
+| `blogs` | `/blog`, `/blog/[id]`, `/blog/category/[id]`, `/blog/page/[p]` |
+| `categories` | `/blog` |
+| `projects` | `/dev`, `/dev/[id]` |
+| `scraps` | `/scraps`, `/scraps/[id]` |
+
+CMS content bodies are rendered as raw HTML via `dangerouslySetInnerHTML`. An inline `<style>` string (`cmsstyle`) is appended to handle code block formatting on detail pages.
+
+Draft preview: `src/middleware.ts` intercepts `?draftKey=` query params and redirects to `/api/draft` for draft mode activation.
+
+### Layout & shared components
+
+- `src/layout/main.tsx` — site-wide shell: announcement banner, header nav (`Blog`, `Dev Projects`, `Apps`, `Scraps`), footer, and `ClickSpark` canvas overlay
+- `src/components/headermeta.tsx` (`HMeta`) — OG/Twitter meta tags; auto-generates OG image via `ogp-img-gen.vercel.app` if no image is supplied
+- `src/libs/gtag.ts` — Google Analytics (GA4 ID `G-9TG7JEDDCX`) pageview/event helpers; called from `_app.tsx` on route changes
+
+### Animation components
+
+All sourced from [reactbits.dev](https://reactbits.dev):
+
+- `AnimatedContent` — GSAP ScrollTrigger slide-in wrapper
+- `SplitText` — GSAP SplitText character/word/line stagger animation
+- `ClickSpark` — canvas spark burst on click (wraps the entire page in `Layout`)
+- `CurvedLoop` / `TextType` — CSS-based marquee and typewriter animations
+
+### Static generation pattern
+
+Content pages use `getStaticPaths` + `getStaticProps` with `fallback: false`. Unpublished items (no `publishedAt`) are excluded from paths and return `{ notFound: true }` from `getStaticProps`.
+
+### Redirect/shortlink pages
+
+Single-character pages (`/g`, `/i`, `/q`, `/x`) and pages under `/l/vx/*` are thin client-side redirects using `useEffect(() => { router.push(url) }, [])`.
+
+### Devmode panel
+
+Detail pages (`/blog/[id]`, `/dev/[id]`, `/scraps/[id]`) render a raw CMS JSON viewer when `process.env.NODE_ENV === 'development'`, toggled by a fixed-position button.
