-> Currently, only **Windows** is fully supported. Support for other platforms may be considered in the future.
+> **Windows** remains the fully supported platform. OpenTabletDriver is Windows-only. On macOS,
+> in-game patching runs the Windows patcher through the same Wine prefix as osu!. The stable
+> patcher stream needs no extra runtime; the experimental stream needs the .NET 8 Desktop Runtime
+> installed in that prefix.
+
+### macOS
+
+osu! stable is a Windows build, so on macOS it runs inside a Wine wrapper. EZPPLauncher
+supports Wineskin wrappers (the usual `osu!.app` wine skin), Whisky bottles and CrossOver
+bottles.
+
+The setup wizard automatically looks for Wineskins in `/Applications` and `~/Applications`.
+If detection fails, choose **Browse** and pick the `osu!.app` wrapper itself (or a Wine prefix
+folder); the launcher resolves the osu! installation inside it, so there is no need to open the
+bundle's package contents.
+
+Large VP8/VP9/AV1 theme videos are transcoded once to a cached 720p H.264/AAC file so WebKit
+can use the Mac's hardware decoder. The first large video triggers a one-time (~63 MB) download
+of a signed static FFmpeg 9.0.2 build from `ffmpeg.martin-riedl.de` into `~/.ezpplauncher/bin`;
+the launcher verifies its pinned SHA-256 and makes it executable. The managed build requires
+macOS 12 or newer. If the download fails, a system FFmpeg (Homebrew or MacPorts) is used; without
+either, themes still load but large WebM videos remain on WebKit's software decoder and may
+stutter. Theme authors can also ship an H.264/MP4 version alongside the WebM.
+
+---
+
+## 🪵 Logs
+
+Launcher, osu! and patcher output is written to `.ezpplauncher/logs` in your home folder:
+
+| File           | Contents                                                       |
+| -------------- | -------------------------------------------------------------- |
+| `launcher.log` | Launcher lifecycle, webview console output and uncaught errors |
+| `osu.log`      | osu! and osu! updater output, including stdout/stderr          |
+| `patcher.log`  | Patcher output, including stdout/stderr                        |
+
+A file is only created when that stream actually writes a line. On each new session, or when
+any file reaches 5 MiB, all three active files are bundled into a single
+`logs_<date>_<time>.zip`; the five most recent bundles are kept. You can turn file logging off,
+open the folder, or browse and filter a bundle in the built-in viewer from **Settings → Logging**.
+On Windows the folder is `%USERPROFILE%\.ezpplauncher\logs`.
+
+**Settings → Diagnostics** checks the selected osu! install and write access, the macOS Wine
+prefix/runtime/version and (for the experimental patcher stream) its .NET 8 runtime, the FFmpeg
+theme-video transcoder, osu-winello/wmctrl on Linux, and whether the patcher is present. It can
+copy a plain-text support report or reopen the setup wizard for a guided repair.

+## 🎨 Launcher Themes
+
+By default, the launcher includes several downloadable themes. Themes can be created
+in two ways:
+
+- Use the built-in **advanced editor** on the Themes screen. It opens in its own
+  resizable window with a full launcher home canvas, freeform text/image/video/shape
+  layers, WebM support, `@fontsource` fonts and custom font imports. It creates API 2.0
+  themes and can export them as shareable `.ezpplauncher-theme` files.
+- Use the [create-ezpplauncher-theme](https://git.ez-pp.farm/EZPPFarm/create-ezpplauncher-theme)
+  CLI. It supports both API 1.0 Svelte themes and API 2.0 declarative themes.
+
+See [THEME_API_V2.md](THEME_API_V2.md) for the full API 2.0 schema, limits and packaging
+layout. API 1.0 themes continue to load unchanged.

+# EZPPLauncher Theme API 2.0
+
+API 2.0 is a declarative theme format. Instead of shipping a JavaScript bundle that
+mounts its own UI, a theme describes its background, effects, audio, fonts and
+freeform layers in `theme.json`. The launcher renders it, and the built-in advanced
+editor can create and edit these themes without writing code.
+
+API 1.0 themes continue to work unchanged. Pick the API that fits the theme:
+
+|                         | API 1.0                                           | API 2.0                                        |

+  font.woff2
+  preview.png        # optional thumbnail

+### Metadata
+
+| Field         | Type   | Required | Notes                                               |
+| ------------- | ------ | -------- | --------------------------------------------------- |
+| `name`        | string | yes      | Display name; also used for the install folder      |
+| `version`     | string | yes      | Semver, used for update checks                      |
+| `apiVersion`  | string | yes      | Must start with `2` (use `"2.0"`)                   |
+| `author`      | string | yes      | Shown in the theme manager                          |
+| `description` | string | no       | Shown on the theme card                             |
+| `nsfw`        | bool   | no       | Marks the theme as adult content (`18+` badge)      |
+| `preview`     | string | no       | Card thumbnail; the editor generates `preview.png`  |
+| `accentColor` | string | no       | Hex color used for focus rings and active UI states |
+| `css`         | string | no       | Extra CSS injected while the theme is active        |
+
+### Background
+
+`background.type` selects the layer:
+
+```json
+{ "type": "color", "color": "#181825", "opacity": 1 }
+```
+
+```json
+{ "type": "gradient", "from": "#181825", "to": "#3b1d4f", "angle": 135, "opacity": 1 }
+```
+
+```json
+{ "type": "image", "src": "background.png", "fit": "cover", "opacity": 1, "blur": 0 }
+```
+
+```json
+{
+  "type": "video",
+  "src": "background.webm",
+  "fit": "cover",
+  "opacity": 1,
+  "blur": 0,
+  "muted": true
+}
+```
+
+- `src` is relative to the theme's `assets/` folder.
+- `fit` is `cover` (default) or `contain`.
+- `opacity` is clamped to `0`–`1`, `blur` to `0`–`40` pixels.
+- Background videos autoplay and loop. They are muted by default; set `muted` to `false`
+  to play their audio.
+- Prefer **WebM** for video backgrounds and video layers. It is supported by the
+  launcher and keeps theme packages much smaller than MP4. MP4, MOV and M4V also
+  work.
+
+### Overlay
+
+```json
+{ "color": "#000000", "opacity": 0.2, "vignette": 0.35 }
+```
+
+`opacity` controls the flat dim layer and `vignette` darkens the edges. Both are
+clamped to `0`–`1`.
+
+### Effects
+
+```json
+{ "type": "stars", "density": 40, "speed": 1, "color": "#ffd6f2" }
+```
+
+Supported types: `none`, `stars`, `snow`, `petals`, `bubbles`.
+
+- `density` is clamped to `0`–`120` particles.
+- `speed` is clamped to `0.2`–`3`.
+- Effects are disabled when the user turns on **Reduce animations**.
+
+### Audio
+
+```json
+{ "src": "music.mp3", "loop": true }
+```
+
+`src` is relative to `assets/`. Music uses the launcher's volume control and is
+silent in the theme editor preview.
+
+### Typography
+
+`typography.body` changes the font used by the launcher UI. `typography.heading`
+changes headings such as the launcher title.
+
+```json
+"typography": {
+  "body": "Montserrat Variable",
+  "heading": "Playfair Display Variable"
+}
+```
+
+These families ship with the launcher through `@fontsource` and can be used
+without adding any files:
+
+| Family                      | Style   |
+| --------------------------- | ------- |
+| `Sora Variable`             | Sans    |
+| `Montserrat Variable`       | Sans    |
+| `Bebas Neue`                | Display |
+| `Playfair Display Variable` | Serif   |
+| `Space Mono`                | Mono    |
+| `JetBrains Mono Variable`   | Mono    |
+
+Custom fonts can be packaged with the theme. The launcher generates the
+`@font-face` rules from `fonts`:
+
+```json
+"fonts": [
+  { "family": "My Display Font", "src": "display.woff2", "weight": "400", "style": "normal" }
+]
+```
+
+- `src` is relative to `assets/`.
+- Supported formats: WOFF2 (recommended), WOFF, TTF and OTF.
+- `weight` defaults to `400`; `style` defaults to `normal`.
+- Use the `family` value in `typography` and in text layers.
+
+The editor's **Fonts** tab browses the full Fontsource catalog (2,000+ families)
+and downloads the selected family, weight, style and subset as a WOFF2 into the
+theme's `assets/` folder. It adds the matching `fonts` entry automatically, so
+saved and exported themes stay self-contained.
+
+### Freeform layers
+
+`elements` are rendered above the launcher UI, but only on the **Home** screen.
+The launcher canvas is a fixed **1000 × 650** coordinate space. Elements can extend
+the home screen with text, images, videos and shapes, and they are
+pointer-transparent in the running launcher so they never block buttons.
+
+The order of the `elements` array controls stacking: the last element is drawn on
+top. Themes can contain up to 100 layers.
+
+Every layer supports:
+
+| Field      | Type    | Notes                                            |
+| ---------- | ------- | ------------------------------------------------ |
+| `id`       | string  | Unique within the theme                          |
+| `name`     | string? | Optional editor label; does not affect rendering |
+| `type`     | string  | `text`, `image`, `video` or `shape`              |
+| `x`, `y`   | number  | Position in the 1000 × 650 stage                 |
+| `width`    | number  | 24–1000                                          |
+| `height`   | number  | 24–650                                           |
+| `rotation` | number  | Degrees, `-360`–`360`                            |
+| `opacity`  | number  | `0`–`1`                                          |
+| `hidden`   | boolean | Keep the layer in the file but do not render it  |
+| `locked`   | boolean | Prevent moving/resizing the layer in the editor  |
+
+#### Text
+
+```json
+{
+  "id": "greeting",
+  "type": "text",
+  "text": "Welcome back!",
+  "x": 360,
+  "y": 220,
+  "width": 420,
+  "height": 90,
+  "fontFamily": "Bebas Neue",
+  "fontSize": 42,
+  "fontWeight": 600,
+  "color": "#ffffff",
+  "align": "center",
+  "verticalAlign": "center",
+  "lineHeight": 1.2,
+  "letterSpacing": 0
+}
+```
+
+`align` is `left`, `center` or `right`; `verticalAlign` is `top`, `center` or
+`bottom`. Font size is clamped to `6`–`240`.
+
+#### Image and video
+
+```json
+{
+  "id": "logo",
+  "type": "image",
+  "src": "logo.png",
+  "x": 700,
+  "y": 420,
+  "width": 220,
+  "height": 140,
+  "fit": "contain",
+  "radius": 18,
+  "opacity": 1
+}
+```
+
+```json
+{
+  "id": "ambient",
+  "type": "video",
+  "src": "ambient.webm",
+  "x": 0,
+  "y": 0,
+  "width": 1000,
+  "height": 650,
+  "fit": "cover",
+  "opacity": 0.35
+}
+```
+
+Video layers autoplay and loop. They are muted by default; set `muted` to `false` to
+play their audio. WebM is recommended for size. Use an `opacity` below `1` if the video
+should blend into the launcher UI.
+
+#### Shape
+
+```json
+{
+  "id": "glow",
+  "type": "shape",
+  "shape": "ellipse",
+  "x": 680,
+  "y": 60,
+  "width": 260,
+  "height": 260,
+  "fill": "#ff006e",
+  "opacity": 0.18,
+  "borderWidth": 0,
+  "borderColor": "#ffffff"
+}
+```
+
+`shape` is `rectangle`, `ellipse` or `line`. `radius` rounds rectangle corners.
+`borderWidth` is clamped to `0`–`40`.
+
+### Custom CSS
+
+The `css` field is appended while the theme is active. Theme authors can use it for
+small tweaks, but it is not required. Example:
+
+```css
+:root {
+  --radius: 1rem;
+}
+```
+
+---
+
+## Using the advanced editor
+
+1. Open **Themes** in the launcher.
+2. Select **Create theme**, or the pencil button on an installed API 2.0 theme.
+3. The editor opens in its **own resizable window**, not a modal. The center is a
+   full launcher home canvas at 1000 × 650.
+4. Use the left toolbar to add text, image, video and shape layers. Drag layers on
+   the canvas, resize with the corner handles, or edit exact values in the right
+   inspector. Shift/Cmd-click a layer or drag a marquee over empty canvas to
+   select several layers. Multi-selections can be dragged together and aligned
+   or distributed from the right panel. Layers snap to canvas edges, the canvas
+   center, and other layers while dragging; hold Alt to disable snapping.
+   Right-click a layer for quick duplicate, ordering, hide/lock and delete
+   actions, or right-click empty canvas to add a new layer.
+5. The layer list supports double-click rename, hide/show, lock/unlock and
+   drag-to-reorder. Hidden layers remain in the package, while locked layers
+   cannot be moved or resized on the canvas.
+6. Use the **Theme** tab for metadata, background, effects, typography and custom
+   CSS. Open the **Fonts** tab to search and download from every Fontsource
+   family, or import WOFF2, WOFF, TTF and OTF files. Downloaded fonts are copied
+   into the theme's `assets/` folder when you save.
+7. Select **Save theme** to write `theme.json` and copy new assets into
+   `~/.ezpplauncher/themes`. A fresh `assets/preview.png` thumbnail is rendered
+   from the theme and the launcher applies the saved theme immediately. Unsaved
+   edits are autosaved as a local draft and offered for recovery after a crash.
+8. Select **Export** to create a shareable `.ezpplauncher-theme` package. A theme
+   check runs first and reports missing assets, oversized media, missing fonts
+   and unused imports. Export saves and refreshes the preview, then reports the
+   final package size.
+
+Keyboard shortcuts:
+
+- `Cmd/Ctrl+Z` undoes the last change.
+- `Cmd/Ctrl+Shift+Z` or `Ctrl+Y` redoes it.
+- `Cmd/Ctrl+S` saves.
+- `Cmd/Ctrl+D` duplicates the selected layer or multi-selection.
+- `Cmd/Ctrl+A` selects every visible layer.
+- Shift/Cmd-click toggles a layer in the current selection.
+- Arrow keys nudge the selected layer(s) by 1 px; hold Shift for 10 px.
+- `Delete` removes the selected layer(s).
+- Hold Alt while dragging to skip snapping.
+- `Esc` clears the selection or closes an open editor dialog.

+
+## Creating API 2.0 themes with the CLI
+
+The `create-ezpplauncher-theme` CLI includes a **declarative (API 2.0)** template:
+
+```bash
+npx git+https://git.ez-pp.farm/EZPPFarm/create-ezpplauncher-theme.git my-theme
+```
+
+Choose `declarative (API 2.0)`, edit `theme.json`, add files to `assets/`, then run:
+
+```bash
+npm run build
+```
+
+This produces `dist/my_theme.ezpplauncher-theme`. The template also includes
+`preview.html` for a standalone browser preview:
+
+```bash
+npx serve .
+```
+
+---
+
+## Compatibility and limits
+
+- API 2.0 packages must include `theme.json`; `entry` and `style` are not used.
+- Asset paths are resolved inside `assets/`; path traversal is rejected by the
+  import commands.
+- Exports include only `assets/` files referenced by `theme.json` (background,
+  audio, fonts, layers and preview). Orphaned files left in the folder are
+  omitted, which keeps packages small. API 1.0 themes are exported whole because
+  their bundles can load files dynamically.
+- The editor writes `preview.png` whenever you save or export. The generated
+  thumbnail renders the background, effects, launcher UI, theme fonts and
+  freeform layers; custom CSS is not applied to the thumbnail.
+- The theme editor only writes inside `~/.ezpplauncher/themes`.
+- API 1.0 themes are still loaded through their existing `mountTheme` bundle API.
+- API 2.0 themes cannot run JavaScript. Use custom CSS for small visual tweaks, or
+  use API 1.0 when a theme needs a fully custom UI.
+- Freeform layers are decorative, home-screen-only and pointer-transparent; they
+  cannot add interactive controls.

+//! Rotating file logs for the launcher, osu! and the patcher.
+//!
+//! Each stream writes to `~/.ezpplauncher/logs`:
+//!
+//! - `launcher.log` receives everything, including frontend console output.
+//! - `osu.log` receives osu! and its updater, including stdout/stderr.
+//! - `patcher.log` receives patcher output.
+//!
+//! A stream's file is only created when it actually has a line to write, so a
+//! launch without osu!/patcher output never leaves empty files behind. When a
+//! new session starts, or any stream reaches 5 MiB, all three active files are
+//! bundled into one `logs_<date>_<time>.zip` and fresh files are started. The
+//! five most recent bundles are kept, so a support report only needs one file.
+//! `launcher.log` intentionally includes the osu!/patcher entries too. File
+//! logging can be disabled from Settings → Logging; stdout output is unchanged.
