- Add Hidden Vault system: - Secure directory storage under ~/.pixelvr_vault with 0700 permissions. - Cheat-code combo unlocking triggered on full grip squeeze (A-B-B-A-X-Y default, customizable). - Headset removal / face detection gating and inactivity auto-lock. - Automatic download history clearing upon vault lock. - Add File Actions Submenu (Button Y): - In-browser file/folder submenu with Move to Vault, Delete, Move, and Rename. - Recursive folder move to vault with collision handling. - Folder deletion with confirmation dialog. - Enhance VR controllers and interactions: - Dynamic left and right Steam Frame controller render models. - Single laser pointer priority with hand swapping via full grip squeeze. - Fix video format detection: - Correct auto-detection and default projection for high-resolution VR180 SBS media (e.g. 7200x3600). - Visual sharpness & rendering stability: - Render swapchain at native 2160x2160 per eye. - SDF font rendering with RMS pixel footprint and stem darkening. - Razor-sharp procedural UI anti-aliasing and crisp border highlights without distortion. - Add unit test suite (tests/test_vault.cpp) and documentation specs.
