/*
 * myShopping IT admin design system.
 *
 * Structurally adapted from the sidebar-shell architecture proven in the
 * PSC Psychology admin (packages/myshoppingit/psych-vertical/resources/css/
 * psych-admin.css) — a two-variable token system (--color-primary /
 * --color-accent) with the entire tint/shade palette derived at load time
 * via color-mix(), so re-skinning only ever touches two values, never a
 * scattered set of hardcoded hex codes.
 *
 * Brand mapping (not a copy of PSC's palette): PSC's sidebar is teal
 * (their brand primary) with gold as the accent/active-state color.
 * myShopping IT's own design system is blue #032366 + near-black #1D1D1F —
 * mapped here as near-black sidebar (primary) with blue as the accent
 * used for active nav state, links, and primary actions.
