docs: user-facing docs revamp — structured product docs + per-platform setup

Replace the dev/agent-log pages with a proper user-facing doc set:

- Getting Started: Introduction (rewritten), How It Works, Quick Start.
- Host Setup: Requirements, then clean per-platform guides — Ubuntu GNOME,
  Ubuntu KDE, Fedora KDE (new), Bazzite (rewritten) — plus Running as a Service
  (desktop / headless GNOME / headless KDE).
- Connecting: Clients overview, Moonlight, Pairing & Trust.
- Configuration: host.env reference, Host CLI, Troubleshooting.
- The dev/design notes (architecture, roadmap, the deferred design specs, CI)
  move to a clearly-separated "Project & Internals" nav section.

Removes the superseded box-specific pages (gnome-box, headless-box, linux-setup,
overview). status.md (the internal progress tracker, with box IPs) is kept as a
file but dropped from the public nav. Site builds clean.

+title: Connect with Moonlight
+description: Stream from a punktfunk host using any Moonlight client.
+---
+
+punktfunk speaks the **GameStream** protocol, so [Moonlight](https://moonlight-stream.org/) connects
+to it like it would to any GameStream host — no punktfunk-specific app needed. This is the easiest way
+to stream to Windows, Android, the Steam Deck, a browser, or a TV.
+
+## 1. Make sure the host is running
+
+On the host machine, `serve --native` (or your [service](/docs/running-as-a-service)) should be up.
+The host advertises itself on the network, so Moonlight usually finds it on its own.
+
+## 2. Add the host in Moonlight
+
+Open Moonlight. Your host should appear automatically on the same network. If it doesn't, use **Add
+Host manually** and enter the host machine's IP address.
+
+## 3. Pair
+
+Select the host and choose **Pair**. Moonlight shows a 4-digit PIN. On the host, you confirm pairing
+(from the web console, or it accepts the ceremony when armed) — see [Pairing & Trust](/docs/pairing).
+Once paired, Moonlight remembers the host.
+
+## 4. Stream
+
+Pick an app/desktop and start streaming. The host creates a virtual display at the resolution and
+frame rate Moonlight requests (set these in Moonlight's settings), encodes it on the GPU, and streams
+it. Mouse, keyboard, and controllers flow back to the host.
+
+## Tips
+
+- **Set your resolution and frame rate in Moonlight's settings** before connecting — the host matches
+  whatever Moonlight asks for, creating the virtual display at that exact mode.
+- **Codec:** HEVC (H.265) is a good default; AV1 is available if your client supports it.
+- **Bitrate:** start moderate and raise it. For very high bitrates, the native [Apple
+  app](/docs/clients) has a built-in speed test; with Moonlight, set the bitrate manually.
+- Moonlight uses the GameStream protocol, not punktfunk's native FEC/encryption extensions. On a
+  solid LAN this is fine; on a lossy link the [Apple app](/docs/clients) holds up better.
