Initial commit: PDF→static HTML/CSS site generator

main.py converts every PDF in examples/ into a browseable, mobile-responsive
HTML archive under output/ using poppler-utils. Includes the two NETgazet
sample PDFs, project metadata, OpenWolf scaffolding, and README covering
usage, a watch-folder script, and WordPress iframe embedding.

+- **Project:** netgazet — converts NETgazet print PDFs (InDesign-laid-out, ~A3, 16pp) into a static HTML/CSS site under `output/`. Entry point is `main.py`; runs via `python main.py` or `uv run python main.py`. Inputs live in `examples/`.
+- **Conversion approach:** page-as-JPEG via `pdftocairo -jpeg -singlefile -r 150` + responsive `img { max-width: 100% }`. `pdftohtml` was deliberately rejected because its complex-mode output is fixed-pixel and not mobile-responsive. Selectable text is provided as a `<details>` block per page from `pdftotext -layout`, split on form-feed (`\f`).
+- **`pdftocairo` filename quirk:** without `-singlefile` it appends `-<page>.jpg` to the output stem; with `-singlefile` it appends just `.jpg`. The script uses `-singlefile` per page so file paths are predictable.
+- **No third-party Python deps.** Conversion shells out via `subprocess.run([...], check=True)`; `pyproject.toml` keeps `dependencies = []`.
