feat: legacy import — packs, examples, lab, themes, docs, lineage

Import from agentic-semantic-web/ into restructured repo:
- 7 packs (apache, caddy, flask, hugo, nginx, pandoc, python)
- shared error pages (403-503)
- 17 lab experiments (boilerplate, charts, misc)
- 31 example pages (charts, components, content, layout, vault)
- 2 themes (garden, trentuna stub)
- 4 docs (llms.txt, vocabulary, philosophy, agent-directive)
- lineage.md (Pico/Open Props/Charts.css history)
- Hugo mounts for lab/ and examples/

All agentic.css references updated to asw.css.

+# ASW-Hugo Pack
+
+A Hugo theme that outputs pure [Agentic Semantic Web (ASW)](https://trentuna.com/asw/) semantic HTML with `data-*` attributes. Drop it into any Hugo project → content renders through ASW.
+
+## What this is
+
+This pack is an **ASW adapter for Hugo** — not a standalone theme. It makes Hugo output the semantic HTML + data-attribute vocabulary that ASW CSS understands.
+
+```
+Markdown vault (Git)
+  → Hugo + ASW-Hugo pack (layouts emit ASW HTML)
+  → static HTML with ASW CSS + data-* attributes
+  → deploy anywhere
+```
+
+Long-term: trentuna will build a native ASW Site Builder. This pack is the bridge to alpha.
+
+## Install
+
+1. Copy or symlink `packs/hugo/` from the ASW repo into your project's `themes/` directory:
+   ```bash
+   # From the agentic-semantic-web repo root:
+   cp -r packs/hugo/ /path/to/your-site/themes/asw-hugo/
+   # or symlink:
+   ln -s /path/to/agentic-semantic-web/packs/hugo/ /path/to/your-site/themes/asw-hugo
+   ```
+
+2. Add to your `hugo.toml`:
+   ```toml
+   theme = "asw-hugo"
+   
+   [taxonomies]
+     tag = "tags"
+   ```
+
+3. Copy ASW CSS into the theme's static directory:
+   ```bash
+   cp /path/to/agentic-semantic-web/asw.css themes/asw-hugo/static/css/asw.css
+   ```
+   > **Note:** `asw.css` is the `asw.css` file from the ASW repo root. B.A.'s deploy script handles this copy automatically for trentuna-web deployments.
+
+4. **Self-host fonts** (recommended for production): The default `theme.css` imports Inter and
+   JetBrains Mono from Google Fonts. For self-hosted deployment, download the font files and
+   replace the `@import` in `static/css/theme.css` with local `@font-face` declarations.
+   See [google-webfonts-helper](https://gwfh.mranftl.com/) for font download.
+
+## Usage
+
+Write standard Markdown. Hugo renders it through ASW layouts automatically.
+
+### Shortcodes
+
+**Callout block:**
+```
+{{< callout note >}}
+This is a note callout. Types: note, warning, tip, info
+{{< /callout >}}
+```
+Renders as: `<aside data-callout="note">...</aside>`
+
+**Wikilink:**
+```
+{{< wikilink "Page Name" "/path/to/page/" >}}
+```
+Renders as: `<a href="/path/to/page/" data-wikilink>Page Name</a>`
+
+### ASW data-* vocabulary used
+
+See `docs/agent-directive.md` in the ASW repo for the full vocabulary.
+
+| Attribute | Where used | Meaning |
+|-----------|-----------|---------|
+| `data-callout="note\|warning\|tip\|info"` | `<aside>` | Callout block type |
+| `data-wikilink` | `<a>` | Internal vault-style link |
+| `data-role="tag-cloud"` | `<nav>` | Tag navigation |
+| `data-layout="grid"` | `<section>` | Grid layout for list pages |
+| `data-tag` | `<a>` | Tag label on links |
+
+## Decap CMS
+
+The `admin/` directory contains a minimal Decap CMS configuration for browser-based Markdown editing without SSH.
+
+To enable:
+1. Update `admin/config.yml`: set `repo` to your Forgejo repo path
+2. Set `base_url` to your Forgejo instance URL
+3. Deploy the `admin/` directory alongside your Hugo output
+4. Access at `https://yoursite.com/admin/`

+## Alpha scope (April 2026)
+
+- [x] Pack scaffolded: all layouts + partials + shortcodes
+- [x] Tag navigation partial (`tag-nav.html`)
+- [x] Wikilink support (`wikilink` shortcode + `data-wikilink` on list page links)
+- [x] Callout blocks (`callout` shortcode → `<aside data-callout>`)
+- [x] Trentuna theme tokens (`theme.css`: Inter, JetBrains Mono, dark palette)
+- [x] Decap CMS config minimal but functional
+- [ ] Deployed to trentuna-web infra — B.A. task: wire `asw.css` copy + nginx config
+
+## Relationship to existing packs
+
+This pack joins the ASW server/framework integration packs:
+- `packs/nginx/` — nginx serving ASW content
+- `packs/pandoc/` — pandoc converting Markdown → ASW HTML
+- `packs/hugo/` ← **this pack** — Hugo site generation with ASW output
