/*
 * Tools public design system - 2026 overhaul.
 *
 * Stack: Tailwind purged (utility classes) + questo file (componenti + design tokens).
 * Target Performance: Lighthouse Mobile >= 90, LCP < 2s, CLS < 0.05.
 *
 * Principi:
 *  - Mobile-first: media query "min-width" per layout desktop progressivo
 *  - Sidebar = drawer slide-in su mobile, sticky a 280px su desktop >= 1024px
 *  - Tipografia: Inter Variable (single woff2 100-900) con fallback system-stack
 *  - Icone: Lucide SVG inline (zero font dependency)
 *  - Color tokens via CSS custom properties: facili da theming
 *  - Componenti riusabili named .tools-*: card, btn, badge, toast, table, tabs
 *  - Niente !important, niente specificita' artificiosa
