The user said "don't worry about mobile" and that one sentence shaped the whole polish pass. Instead of splitting effort between touch events and responsive breakpoints, the cleanup focused entirely on the desktop WebGL experience — the thing that actually sells a particle galaxy. Added glassmorphic control panels with backdrop-blur-md, three instant presets (Nebula scatters particles into a purple cloud, Singularity cranks twist to −0.8 and lights up the destination core, Calm dials everything to zero), and a Hide UI toggle that strips the chrome so you're just floating in the galaxy. The warp tunnel steers with mousemove — cursor position maps to camera group position through velocity smoothing and a 0.9 damping factor, with roll banking on horizontal steering. The fragment shader adds chromatic aberration that increases with distance from center and brightens on hard turns. Skip mobile, nail the viewport.
