/**
 * Design system ported verbatim from the original FACILINK Performance360
 * single-tenant app's <style> block — same tokens, same component classes
 * (.topbar, .tabs/.tab, .card, .btn variants, .badge, .stat-tile,
 * .bar-row, table.data-table, .rate-btn, .qr-box, .chip-filter,
 * .empty-state, .banner, .kv-list, .expand-row/.expand-panel, print
 * styles for PDF export), so every page built with these classes matches
 * the original pixel-for-pixel — including its automatic light/dark
 * theming via prefers-color-scheme. Every admin-facing page in this app
 * (both /admin/ and /super-admin/) is built using these classes rather
 * than one-off inline styles, specifically so this file is the single
 * place a visual tweak belongs.
