/* JPAccess - liquid-metal CTA treatment (v1)
 *
 * Layers added inside each dark [data-slot="liquid-button"]. The button itself
 * already carries `relative isolate rounded-full`, so it owns a stacking
 * context and negative z-index children stay inside it:
 *
 *   -10  .glass-deep          the bundle's own dark surface + drop shadow
 *    -9  .lm-rim   (canvas)   animated liquid metal, full bleed
 *    -8  .lm-face             black inner pill, inset 2px, leaves the metal rim
 *     0  label                the bundle's own text, untouched
 *     1  .lm-ripples          click ripples
 *
 * Nothing here restyles the bundle's classes; it only adds .lm-* layers, so a
 * rebuilt bundle keeps working with or without this file.
