/*
 * NEXORA Shared UI Primitives — Cycle 008 / task-006
 * -------------------------------------------------------------------------
 * Reusable building blocks consumed by the migrated product screens
 * (tasks 008-018): page header, breadcrumbs, cards/stat cards, buttons,
 * badges, tables, data lists, empty/loading states, key/value blocks, tabs,
 * pagination.
 *
 * This file also BRIDGES the legacy application.css class names (.panel,
 * .button-*, .resource-list, .definition-list, .workspace-panel, ...) onto the
 * NEXORA look so existing screens adopt the system without per-file edits.
 * It must load AFTER application.css so those bridges win the cascade.
