/**
 * theme.css — DeayanXtra Elemental Effects · shared design system
 * =============================================================================
 * Used by BOTH the pack shell (index.html) and every effect studio.
 *
 * Direction: dark studio with a light dot-matrix grid, and light titanium
 * "cards" cut from the same anisotropic brushed metal as the DeayanXtra button.
 * No primary colours anywhere — colour only ever appears as *content*.
 *
 * Every interactive control (sliders, switches, buttons, stops) is a metal part:
 * a conic-gradient anisotropic face, a bevelled edge and an iridescent film.
