The mark is an H whose crossbar is the horizon: a violet line edge to edge, the stems above it
and their reflection below at a third, on whole units of a 16-unit grid so it stays sharp at
16 px. docs/media/brand holds the SVG masters (square icon, macOS tile, avatars, the mark for
light and dark backgrounds), the two alternatives that were shown with it, the GitHub social
preview and the Discord banner, and a README of what goes where and how to upload what only
Ludovic's accounts can.
`cargo run -p xtask -- icons` renders the masters (rsvg-convert) and packs, in plain Rust:
packaging/icons/horizon.ico and horizon.icns, Linux's hicolor icons 16–512 and the scalable
SVG, the game's run-time window icon, the avatars and the website's favicons.
packaging/linux has .desktop entries for the launcher and the game.
On Windows, build.rs embeds the .ico as icon resource 1 in horizon-client (and its tools) and
horizon-launcher (winresource, a Windows-only build dependency); gpui loads that resource as
the launcher's window icon. The game window sets the icon itself (X11, Windows) and names
itself `horizon` on Wayland so the desktop entry matches.
