After Burner II Recomp - Linux x86_64 preview

Extract the entire archive into a folder in Desktop Mode. Add Launch.sh as a
Non-Steam Game. Use the Gamepad controller template, then launch in Gaming Mode.
Run natively; do not select Proton. First-run settings use fullscreen/16:10.
Menus can change both.
Keep lib/ beside the executable. Existing preferences are preserved.

Supply your own verified After Burner II ROM set: put aburner2.zip in roms/,
use the initial file picker in Desktop Mode, or pass --roms /absolute/path.zip.
No game ROMs, recordings, captures, music or saved preferences are included.
Settings and controller bindings are stored under XDG_DATA_HOME (by default
~/.local/share/AfterBurner2-Recomp/AfterBurner2).

Built in Steam Linux Runtime 3 (sniper), x86-64, maximum required glibc 2.31.
SDL3/OpenAL, librashader and any shared C++ runtimes are replaceable files in lib/. The
SDK may link its newer libstdc++ statically; GCC runtime notices are included. System
graphics, window-system and audio drivers remain supplied by the Linux host/runtime.
The exact project snapshot and dependency source archives are supplied in the
sources companion. BUILD.json records the base commit and snapshot hashes.

Preview limitations: Physical Steam Deck performance, controller feel, suspend/resume and audio latency need testing on a Deck. Linux currently
uses the existing worker-thread CPU continuation backend. RetroArch Slang
uses native Vulkan composition with librashader 0.12.0 already bundled in lib/.
No separate shader runtime installation is needed.

To install RetroArch Slang shaders:
1. Download the official Libretro shader pack: https://buildbot.libretro.com/assets/frontend/shaders_slang.zip
2. Extract the entire ZIP into a folder you can keep. Preserve its subfolders,
   shader includes and lookup textures together.
3. Open Settings > CRT and Shaders > Shader Preset and select a .slangp preset
   from that extracted pack. Selection activates RetroArch mode.
Shader packs are external downloads; they are not included in this game archive.
Corresponding bundled-runtime sources and notices: https://github.com/duduke/AfterBurner2-Recomp-Releases/releases/download/v0.1.0-preview.7/librashader-0.12.0-Linux-x86_64-Vulkan.tar.gz
Legacy GLSL/Cg presets, HDR and first-input mipmap generation remain unsupported.
