/*!
 * GINI Design System — "Precision Instrument" modern skeuomorphism
 * https://gini.iq/skeu.css · reference: https://gini.iq/brand#design-system
 *
 * Drop-in, framework-agnostic stylesheet: the --skeu-* tokens plus every
 * skeu-* material/control class used on gini.iq. Works with plain HTML,
 * React, Vue, Tailwind, etc. — add the class, keep your own layout utilities.
 *
 *   <link rel="stylesheet" href="https://gini.iq/skeu.css">
 *   @import url("https://gini.iq/skeu.css");
 *
 * Pair with https://gini.iq/brand.css for the palette / shadcn aliases.
 * RTL: set dir="rtl" on the root (or any subtree); toggles, alerts and rows
 * flip automatically via logical properties and :dir() selectors.
 *
 * Elevation: recessed → well → flush → raised-1 → raised-2 → floating →
 * overlay (+ pressed). One light source, upper-left. Never invent shadows —
 * use the --skeu-shadow-* stacks. Cascade note: the classes are unlayered
 * (they beat layered utilities); `position: relative` is provided at lower
 * priority in @layer components so your sticky/absolute/fixed still win.
 *
 * This file is the single source of truth — gini.iq imports it into its own
 * Tailwind bundle, so what you get here is exactly what the site uses.
