 ### Directory Structure
-- **`src/`** - Main Rust application code
-  - `src/ui/` - Legacy Sciter UI (deprecated, use Flutter instead)
-  - `src/server/` - Audio/clipboard/input/video services and network connections
-  - `src/client.rs` - Peer connection handling
-  - `src/platform/` - Platform-specific code
-- **`flutter/`** - Flutter UI code for desktop and mobile
-- **`libs/`** - Core libraries
-  - `libs/hbb_common/` - Video codec, config, network wrapper, protobuf, file transfer utilities
-  - `libs/scrap/` - Screen capture functionality
-  - `libs/enigo/` - Platform-specific keyboard/mouse control
-  - `libs/clipboard/` - Cross-platform clipboard implementation

-## Important Build Notes
-
-### Dependencies
-- Requires vcpkg for C++ dependencies: `libvpx`, `libyuv`, `opus`, `aom`
-- Set `VCPKG_ROOT` environment variable
-- Download appropriate Sciter library for legacy UI support
-
-### Ignore Patterns
-When working with files, ignore these directories:
-- `target/` - Rust build artifacts
-- `flutter/build/` - Flutter build output
-- `flutter/.dart_tool/` - Flutter tooling files
-
-### Cross-Platform Considerations
-- Windows builds require additional DLLs and virtual display drivers
-- macOS builds need proper signing and notarization for distribution
-- Linux builds support multiple package formats (deb, rpm, AppImage)
-- Mobile builds require platform-specific toolchains (Android SDK, Xcode)
-
-### Feature Flags
-- `hwcodec` - Hardware video encoding/decoding
-- `vram` - VRAM optimization (Windows only)
-- `flutter` - Enable Flutter UI
-- `unix-file-copy-paste` - Unix file clipboard support
-- `screencapturekit` - macOS ScreenCaptureKit (macOS only)
-
-### Config
-All configurations or options are under `libs/hbb_common/src/config.rs` file, 4 types:
-- Settings
-- Local
-- Display
-- Built-in

 ## Rust Rules
 
-- In Rust code, do not introduce `unwrap()` or `expect()`.
-- Allowed exceptions:
-- Tests may use `unwrap()` or `expect()` when it keeps the test focused and readable.
-- Lock acquisition may use `unwrap()` only when the locking API makes that the practical option and the failure mode is poison handling rather than normal control flow.
-- Outside those exceptions, propagate errors, handle them explicitly, or use safer fallbacks instead of `unwrap()` and `expect()`.
+* Avoid `unwrap()` / `expect()` in production code.
+* Exceptions:
+
+  * tests;
+  * lock acquisition where failure means poisoning, not normal control flow.
+* Otherwise prefer `Result` + `?` or explicit handling.
+* Do not ignore errors silently.
+* Avoid unnecessary `.clone()`.
+* Prefer borrowing when practical.
+* Do not add dependencies unless needed.
+* Keep code simple and idiomatic.
+
+## Tokio Rules
+
+* Assume a Tokio runtime already exists.
+* Never create nested runtimes.
+* Never call `Runtime::block_on()` inside Tokio / async code.
+* Do not hide runtime creation inside helpers or libraries.
+* Do not hold locks across `.await`.
+* Prefer `.await`, `tokio::spawn`, channels.
+* Use `spawn_blocking` or dedicated threads for blocking work.
+* Do not use `std::thread::sleep()` in async code.
 
 ## Editing Hygiene
 
-- Do not introduce formatting-only changes.
-- Do not run repository-wide formatters or reflow unrelated code unless the
-  user explicitly asks for formatting.
-- Keep diffs limited to semantic changes required for the task.
+* Change only what is required.
+* Prefer the smallest valid diff.
+* Do not refactor unrelated code.
+* Do not make formatting-only changes.
+* Keep naming/style consistent with nearby code.
