Add nav/footer, contact form, privacy/terms drafts, first course landing page

- baseof.html: proper header/nav/footer, CSS custom properties for
  light/dark, button and form component styles — no external theme
  dependency, avoiding the submodule/version churn from the earlier
  PaperMod attempt.
- Contact page: real form (honeypot spam protection) posting to the eec
  service's new /contact endpoint, replacing the plain mailto CTA.
- Privacy Policy and Terms drafts — grounded in what's actually true here
  (self-hosted mail/course infra, no third-party trackers), flagged as
  drafts pending review.
- courses/ section with a generic single template driven by front matter
  (eec_slug, pitch) and the first course, Find Your Right Readers —
  landing page only; the actual course content isn't authored in
  eec-courses yet, so enrolling will 404 until that's written.
- Fixed hugo.toml baseURL (was www.reground.org, but Caddy's canonical
  host is the bare domain — www redirects to it, not the other way).

+title: "Terms of Use"
+description: "Terms for using reground.org and its email courses."
+---
+
+_Last updated: July 2026_
+
+**This is a draft.** It hasn't been reviewed by a lawyer. Review before treating it as final.
+
+These terms cover using reground.org, its free email courses, and
+submitting the contact form. They don't cover the terms of any paid
+coaching, ghostwriting, or consulting engagement — those are agreed
+separately, in writing, before any paid work begins.
+
+## Using this site
+
+This site and its free email courses are provided as-is, for informational
+and educational purposes. Nothing on it is professional advice specific to
+your situation — it's general guidance, and you're responsible for how you
+apply it.
+
+## Email courses
+
+Course content is mine, written for general educational use by whoever
+signs up. You're welcome to apply what you learn to your own work; you're
+not entitled to redistribute, resell, or republish the course content
+itself without asking first.
+
+## No warranty
+
+This site and its content are provided without warranties of any kind,
+express or implied. I make a good-faith effort to keep things accurate and
+working, but I don't guarantee any particular outcome from taking a free
+course or reading anything published here.
+
+## Liability
+
+To the extent the law allows, I'm not liable for damages arising from your
+use of this site or its content. If you're looking for guarantees around a
+specific outcome, that belongs in a paid engagement's written agreement,
+not these terms.
+
+## Changes
+
+I may update these terms as the site changes. Material changes will update
+the date at the top of this page.
