Added staging.nginx.nix modeled on prod.nginx.nix, configuring nginx as a
local staging server. Updated deploy.sh to target either staging or prod
over SSH. Consolidated shared configuration between the two nginx nix
files and between the staging and prod deploy paths in deploy.sh.
Bootstrapped the site from scratch following a data loss event. Set up a
simple HTML/CSS page served from nginx. Added a navbar with the index page
anchored in the top-left, a blog page link, and a link to the Forgejo
instance. Added contact info and a genealogy blurb to the index page.
Added an example resume page linked from the navbar.
