"""Assemble the website payload in work/site-stage, laid out as on the server.

    py scripts/stage_site.py

The server serves /var/www/lihont. Pages that live in folders (/lihonb, /members, /pay) are
index.html files there. Only files that belong to the site redesign are staged: the pages and
src/web/assets/site/{md3.css,md3.js,icons.svg}. Existing downloads, logos and the old
md3-theme.css (used by the member portal) are not touched.
