/*
 * Kleren Inventory — Design System
 * Hybrid: Vasy-style info-density + modern SaaS polish (Linear/Stripe vibe).
 *
 * Usage: Every /inventory-*.html page includes this CSS and uses iv-* classes.
 * Keep page-specific styles to a minimum — push reusable patterns up to here.
 *
 * Naming: every class is prefixed `iv-` so it can't clash with shared style.css.

   the screenshots flagged). */
