STYGION Launcher a0.8.1

Fixes

• The Linux launcher opens, not just its window. The downloaded AppImage came up as a grey rectangle: it carried libwayland-client from the machine that built it, that one shadowed the one on the user's computer, and the graphics driver then refused to load. The WebView had nowhere to draw and died before anything appeared. Only what genuinely belongs to the app is bundled now; the rest comes from the system, as it should. Windows and macOS are unchanged.
• The mark is the mark again. In the titlebar, on the welcome screen, in Settings → About and during an update, the logo was read from a file whose transparency had been flattened onto white somewhere along the way — a white square sat beside the mark, and a filter was layered on top everywhere to hide it. Mark and lettering now come from the masters, unfiltered, sharp at every size.
