- Add data/editions.js (SVG path data for all editions, was missing from repo)
- Add CNAME for custom domain plotflow.io
- Add .nojekyll to disable Jekyll processing
- Add .gitignore for common OS artifacts

-# PLOTFLOW · design system + homepage
+# PLOTFLOW — plotflow.io
 
-Avant-garde pen-plotter art house. Muted ground, bold white grotesque, Japanese, halftone + asterisk, with an interactive **Live Plot** hero that draws each mobile-suit plot as one continuous line.
+Static website for PlotFlow, an avant-garde pen-plotter art house. No build step, no framework — plain HTML/CSS/JS served via GitHub Pages.
 
-## Quick start
-
-No build step or dependencies — it's static HTML/CSS/JS with the data inlined in a script.
+## Run locally
 
 ```bash
-# just open it…
-open index.html                      # works from file://
-
-# …or serve it (recommended)
-python3 -m http.server 8000          # then visit http://localhost:8000
+python3 -m http.server 8000
+# visit http://localhost:8000
 ```
 
-`preview.html` is a single-file, fully-inlined version of the same page (handy for a quick look or to drop into a CMS).
+## Deploy
 
-## Structure
+Push to `main`. GitHub Pages serves from the repo root automatically.
 
+```bash
+git add -A && git commit -m "update site" && git push
 ```
-plotflow-design-system/
-├─ index.html            # the homepage (links the css + scripts below)

-└─ docs/
-   └─ DESIGN_SYSTEM.md   # tokens, components, rules — start here
-```
-
-## Common edits
 
-**Change the palette / type** → edit `styles/tokens.css` (and mirror in `tokens.json`). Everything reads those variables.
-
-**Add or change an edition**
-1. Drop the new clean SVG in `assets/plots/` (run `python tools/prep_plots.py raw/` if it's a fresh plotter.vision export).
-2. Add a row to `META` (and the order arrays) in `tools/build_data.py`.
-3. `python tools/build_data.py` → regenerates `data/editions.js`. Done; the shop + plotter pick it up.
-
-**Plot legibility** — keep the cardinal rule: show plots large with a thin stroke; don't scale a plot up to fill a small card (it fuses the lines). Stroke widths are set in CSS (`.hero #ppath`, `.card .cover .art path`).
+## Structure
 
-See `docs/DESIGN_SYSTEM.md` for the full spec and `CLAUDE.md` for working in this repo with Claude Code.
