docs: Englische README-Uebersetzung (README.en.md)

Deutsch bleibt Quellsprache (CLAUDE: "Doku auf Deutsch"), daher die
Uebersetzung als separate README.en.md statt README.md zu ersetzen.
Wechselseitige Sprachlinks oben in beiden Dateien; Hinweis in der
englischen Fassung, dass sie eine Convenience-Uebersetzung ist und der
deutschen Vorlage hinterherhaengen kann.

+A textual, Markdown-like notation for work breakdown structures with
+and/or decomposition — plus a live editor that renders it as a diagram.

+`-` = mandatory sub-package (all of, side by side in the diagram) ·
+`|` = alternative (any of, stacked) · `[…]` = status ·
+`(M)` = T-shirt effort · `@name` = responsibility · `%%` = comment.
+
+## Usage
+
+Open `frontend/index.html` in the browser — edit text on the left, the
+diagram is built live on the right. Toggles: transposed (narrow) layout,
+show discarded elements.
+
+## Project documents
+
+- `frontend/` — editor · `backend/` — Kotlin/Spring (scaffold to follow, see backend/README.md)
+- `docs/SPEC.md` — normative language definition
+- `docs/DECISIONS.md` — design decisions with rationale
+- `docs/ROADMAP.md` — Mermaid plugin, Taiga integration, Tenzu
+- `docs/TASKS.md` — open tasks (checkboxes)
+- `docs/brand/BRAND.md` — logo, wordmark, usage rules
+- `docs/design/` — design derivation of the brand
+- `CLAUDE.md` — project context for Claude Code
+
+> **Note:** The project documentation is maintained in German; German is the
+> source language (see `CLAUDE.md`). This English README is a convenience
+> translation and may lag behind the German original.
+
+## Deployment
+
+The editor is published as a static page on **GitHub Pages** via GitHub
+Actions (workflow: `.github/workflows/pages.yml`). Triggered on every push to
+`main` and manually (`workflow_dispatch`).
+
+The workflow assembles a site folder: `frontend/index.html` is placed as
+`index.html` at the root URL, along with the files the editor references
+(`docs/brand/` for the favicon, `LICENSE` for the MIT link in the footer). The
+`../` paths in the editor source are straightened only on the copy — the source
+file stays unchanged. `backend/` and the remaining `docs/` are not published.
+
+**One-time setup:** In the repo settings under **Pages**, select **Source** =
+"GitHub Actions". The repo must be **public** for this (GitHub Pages via Actions
+is only available for private repos on a paid plan).
