**Hypercolor's pitch:**

> "Everything proprietary tools do, but open source, Linux-native, and yours to keep."

| Dimension | Closed-Source Alternative | Hypercolor |
| ------------------------ | ---------------------------- | ------------------------------------ |
| **Platform** | Windows only | Linux-first (future: cross-platform) |
| **License** | Proprietary | Apache-2.0 |
| **Effect compatibility** | Native | ~90% via Servo compatibility layer |
| **Effect format** | HTML/Canvas (proprietary) | HTML/Canvas + native wgpu shaders |
| **Performance** | 60fps (proprietary renderer) | 60fps (Servo) + 1000s fps (wgpu) |
| **Customization** | Limited (closed source) | Infinite (modify anything) |
| **Price** | Free tier + subscription | Free forever |
| **Community effects** | Curated store | Open marketplace (GitHub) |
| **Smart home** | None | Home Assistant integration |

**Key narrative:** Hypercolor doesn't need to beat closed-source tools on Windows. It needs to be **so good on Linux** that Windows users consider switching. The existence of a compelling open-source alternative creates pressure regardless.

Align the roadmap with the current platform claim.

The table now presents Linux, Windows, and macOS support as current. Lines 1407 and 1420 still schedule cross-platform support for later years. Update those roadmap entries so this document matches the current platform descriptions in docs/content/_index.md.

**Key narrative:** Hypercolor meets the closed-source tools on their own platform and everywhere else. It needs to be **so good on every desktop** that vendor apps have nothing left to offer. The existence of a compelling open-source alternative creates pressure regardless.

Hypercolor isn't just software. It's the argument that open source can do creative, visual, hardware-integrated things better than closed-source alternatives. And it's built by someone who has proven that argument before.

Hypercolor is Linux-first, but the architecture isolates platform-specific code behind trait boundaries. This section catalogs what is universal and what needs platform-specific implementations.

**Design principles:**

- **Linux-first.** D-Bus (logind, freedesktop screensaver) and kernel (evdev) are the primary backends. Cross-platform can follow later.
- **Native backends per platform.** D-Bus (logind, freedesktop screensaver) and kernel evdev on Linux, `WM_POWERBROADCAST` plus WTS session events on Windows, and NSWorkspace plus IOKit power notifications on macOS, all feeding the same `SessionEvent` stream.
- **Event-driven, not polling.** Subscribe to D-Bus signals and kernel input events. No timers ticking to check state, except as a fallback for idle detection on X11.
- **Graceful degradation.** Each monitor is independent. If logind is unreachable (container, WSL), the screensaver monitor still works. If neither D-Bus bus is available, the daemon runs without session awareness.
- **Inhibitor-aware.** Acquire a logind sleep inhibitor lock so the daemon can complete its fade-out before the kernel actually suspends.
