New builds write path-relative PDF annotations so the tree can be served
from docs.verae-time.net (or any host at the site root) without a rebuild.
scripts/rewrite-docs-host.py retargets an already-built site when absolute
URLs are preferred. Live service doors stay on their own hostnames.
Module and model book cards now point at generated index.html/index.pdf
instead of directory URLs that 404. WeasyPrint file:// annotations are
mapped to https://zapier.georgelambert.org/ paths that exist. Developer
module, architecture, and research snapshot links target published files.
