/**
 * nw-components.css
 * NukeWorker Shared Component Library — ACTIVE subset
 *
 * Loaded on every page. Contains only :root design tokens + the components
 * that pages actually reference today. Slim by design to keep critical-path
 * CSS small.
 *
 * The FULL forward-looking design system (KPI, badge, btn, alert, table,
 * controls, grid, tip, status-dot, pill-nav, search, collapse) lives in
 * /includes/nw-components-library.css and is NOT loaded site-wide. When a
 * page is ready to adopt one of those components, copy the relevant rules
 * over here (or load the library on that page specifically).
 *
 * Active components:
 *   - Card (.nw-card, .nw-card-header, .nw-card-body, .nw-card--static)
 *
 * Dark mode overrides use body.theme-nuclear from dark_colors.css.

   DESIGN TOKENS
   Self-contained :root so tokens are available even when nuke2026a.css
   is not loaded (most pages load nuke2026.css instead). Values are
   intentionally identical to nuke2026a.css — whichever loads last wins
   with the same result.
