Initial scaffold: reader-magnet course stub for thistleandmoth.org

Mirrors michaelferrara-eec-courses. course.yml is active: false and
all copy is TODO until the real reader-magnet file/cover art are
ready and the thistleandmoth-list Listmonk list exists.

+# thistleandmoth-eec-courses
+
+Course content for [eec](https://gitea.reground.org/will/eec), the self-paced
+email course engine — this instance served at eec.thistleandmoth.org. Push to
+`master` and CI syncs `courses/` straight to production — there's no staging
+step, so treat a push here the same as a push to `eec` itself.
+
+Full reference for course/step file format, `course.yml` fields, the
+readiness step, drip-triggered courses, and sync guardrails lives in the
+[`eec-courses`](https://gitea.reground.org/will/eec-courses) README — the
+format is identical, only the target instance differs.
+
+## Layout
+
+```
+courses/
+  reader-magnet/
+    course.yml
+    day-0.md
+    day-1.md
+```
+
+`reader-magnet` is the funnel for thistleandmoth.org's `/gift` page (see the
+`thistleandmoth-site` repo). Same shape as michaelferrara.org's: landing page
+signup → subscriber added to the thistleandmoth.org Listmonk list immediately
+(`signup_list_name` in `course.yml`, no click required) → the reader-magnet
+file email goes out (`{{.CTALink}}` in `day-0.md` is a direct download link,
+not a webpage) → a day-1 follow-up email 24h later with no list/conversion
+mechanics of its own.
+
+## Stub — two things need to happen before this goes live
+
+1. **`course.yml` is `active: false`.** All the content below is a
+   placeholder (TODO subject lines, TODO body copy, and a `redirect_url`
+   pointing at a file that doesn't exist yet in the `thistleandmoth-downloads`
+   bucket — see `thistleandmoth-site`'s `/gift` page, which is the same kind
+   of stub). Replace the TODOs with real copy once the reader-magnet file and
+   cover art are ready, then flip `active: true`.
+2. **`signup_list_name: "thistleandmoth-list"` doesn't exist yet in
+   Listmonk.** Sync rejects the course outright if the name doesn't resolve
+   to exactly one list — create that list in the Listmonk admin UI first
+   (matching the naming convention of `michaelferrara-list` /
+   `Two Squirrels Press`), then push.
+
+Until both of those are done, CI runs against this repo will fail sync with
+a clear error — that's expected, not a sign anything's broken.
+
+## Deploying
+
+Push to `master` → `.gitea/workflows/sync.yml` tars up `courses/` and
+`POST`s it to this domain's `eec-thistleandmoth` container over the internal
+Docker network, authenticated with `THISTLEANDMOTH_EEC_SYNC_TOKEN` (a Gitea
+Actions secret shared with the `eec-thistleandmoth` Ansible role's copy). No
+separate deploy step, no staging — a push here goes live immediately (once
+`active: true` and the Listmonk list exist).
