/* Toast + confirm system — structure + motion only.
   Atmosphere-correct COLOR comes from Tailwind gray-scale utility classes
   (.bg-white / .text-gray-900 / .text-gray-600 / .border-gray-200 / .bg-gray-100 /
   .bg-blue-600), which the atmosphere system remaps per body[data-atmosphere]
   across all 20 atmospheres (see static/css/atmospheres*.css). This file owns only
   layout, radius, depth, the refraction sheen, the semantic tone strip/icon (a thin
   fixed-hue non-text accent, safe on any atmosphere), and motion. All motion is gated
   behind html.tx-motion exactly like the boot overlay, so the motion-intensity slider's
   hard floor and OS prefers-reduced-motion both pin these to an instant presentation. */
