   Material notes
   · Glass = dark frosted tint + a faint sheen lit by the current
     environment light (--vx-env-light, set by env.js) + a 1px
     specular rim (::before) that leans toward the pointer
     (--vx-lx / --vx-ly, set by ui.js) + neutral soft shadows.
   · .vx-glass::before is reserved for the rim, .vx-hover::after
     for the gaze glow. Use other pseudo elements in your files.
