Builds with the `dlss` feature use NVIDIA DLSS through Bevy's `dlss_wgpu` (MIT
OR Apache-2.0). NVIDIA's runtime `nvngx_dlss.dll` and its notices,
`NVIDIA-DLSS-NOTICE.txt`, ship beside the exe. Neither the DLSS SDK nor the DLL
is in this repository. See `docs/dlss.md`.

The Steam relay ships Valve's `steam_api64.dll` from the Steamworks SDK
redistributables, under the Steamworks SDK Access Agreement. It is not in this
repository.

The launcher's interface embeds Big Shoulders Display, Barlow and IBM Plex Mono
(Latin subsets from Google Fonts) under the SIL Open Font License 1.1. Their
copyright lines and the full license text are in
`crates/skate-launcher/ui/fonts.html`, which is built into the launcher.

The launcher's Discord button shows the Discord logo, a trademark of Discord Inc., used to link to the project's
Discord server. Its outline is the `discord` icon of Simple Icons 13.21.0 (https://simpleicons.org, CC0 1.0).

## Skate 2 Rust port (MIT)

`vendor/skate2-rust-port/` holds the simulation crates (`skate2-core`, `skate2-formats`) of skate6743's Skate 2 Rust
port, https://github.com/skate6743/skate2-rust-port, commit f72f2c1302bf9cf176f842ace7b441d1824feba4 (v0.2.3). They are
copied unchanged except the lines marked `ENGINE HOOK (user 10-20)`, which `vendor/skate2-rust-port/VENDORED.md`
lists. The Skate 2 physics setting runs them in a separate program, `skate2-physics-host`. License: MIT, Copyright (c)
2026 skate6743 and contributors. The license text is `vendor/skate2-rust-port/LICENSE` in the source and
`licenses/skate2-rust-port.txt` in the release package. No Skate 2 game data is bundled: the player's own disc
supplies it.
