Replace Astro/Strapi site with Next.js static export

- Fresh structure: Next.js App Router + Tailwind v4 at the repo root, exported
  as static files (output: export) and served by static-web-server
- Remove the Strapi CMS, Astro app, Pagefind search, comments, old scripts,
  Lighthouse config and compose files; content in content/ is now plain
  markdown with YAML frontmatter
- Pages: About, Writing, Reading (3D bookshelf) and Portfolio, styled after
  adammaj.com
- SEO: metadata and canonicals, JSON-LD, generated OG images, sitemap, robots,
  RSS and JSON feeds, llms.txt
- Umami via PUBLIC_UMAMI_SCRIPT_URL / PUBLIC_UMAMI_WEBSITE_ID (build args)
- Dockerfile builds the export and serves it with sws.toml (security headers,
  clean URLs, .well-known, OG image content type, immutable asset caching)
- Prettier and cspell for content with a husky/lint-staged pre-commit hook
- Old redirect list dropped to start from a clean slate

 # andwati.com
+
+Personal site: about, writing, reading and portfolio. Next.js (App Router) with Tailwind CSS v4, exported as static files and served by [static-web-server](https://static-web-server.net/).
+
+## Develop
+
+```sh
+pnpm install
+pnpm dev
+```
+
+## Content
+
+Everything lives in `content/` as markdown with YAML frontmatter:
+
+- `content/about.md` is the home page
+- `content/writing/*.md` are posts (`title`, `description`, `date`, `tags`)
+- `content/reading/*.md` are books and papers
+- `content/portfolio/*.md` are projects
+
+Covers go in `public/covers/<slug>.jpg`. Math (`$...$`), code fences, callouts and YouTube embeds are supported.
+
+## Checks
+
+```sh
+pnpm check           # Biome (code) + Prettier and cspell (content)
+pnpm format:content  # format markdown
+```
+
+A pre-commit hook runs these on staged files. Add project words to `.cspell/words.txt`.
+
+## Analytics
+
+Umami is loaded when both variables are set **at build time**:
+
+```
+PUBLIC_UMAMI_SCRIPT_URL=https://analytics.andwati.com/script.js
+PUBLIC_UMAMI_WEBSITE_ID=...
+```
+
+## Deploy
+
+```sh
+docker build -t andwati-site \
+  --build-arg PUBLIC_UMAMI_SCRIPT_URL=... \
+  --build-arg PUBLIC_UMAMI_WEBSITE_ID=... .
+```
+
+The image builds the static export (`out/`) and serves it with `sws.toml` (security headers, clean URLs, `.well-known`). In Dokploy, pass the two Umami variables as build args.
