3D view unavailable

This viewer needs WebGL2.

To fix this:

• Chrome/Edge: open chrome://gpu — “WebGL2” should say Hardware accelerated. If not, enable Settings → System → Use hardware acceleration, then relaunch.
• Firefox: open about:support and check “WebGL 2 Driver Renderer”. If blocked, set webgl.disabled = false and webgl.force-enabled = true in about:config.
• Safari: Settings → Advanced → “Show Develop menu”, then Develop → check WebGL is enabled (older Safari hid WebGL 2.0 under Develop → Experimental Features).
• Privacy tools: Brave “Block fingerprinting”, Tor, or anti-fingerprint extensions disable WebGL — allow it for this site.
• Remote desktop / VM with no GPU: launch the browser with a software backend, e.g. Chrome --use-gl=angle --use-angle=swiftshader.

The cipher engine itself is independent of the 3D layer — run npm test or open tests/engine.test.html.
