Panels

React + Vite + TypeScript + Tailwind 4 + shadcn/ui (style radix-nova, base color neutral, lucide icons), pnpm. The same components.json everywhere, with the @xvii registry added (see services/ui.md).
Components come only from shadcn: upstream (pnpm dlx shadcn@latest add …) and @xvii. src/components/ui and src/components/xvii are generated: don't edit them by hand. Tailwind classes only for layout; no custom CSS.
Every panel uses the @xvii/app-shell: sidebar with the service's sections, service switcher, team switcher, account menu, ⌘K command menu, theme and language toggles. Routes are paths; the binary serves index.html for unknown paths.
Responsive: phones get item lists instead of tables (DataTable renderMobile) and drawers instead of dialogs (ResponsiveDialog); tablets hide secondary columns and fold the sidebar to icons. Pass stable arrays to DataTable (memoize): a new array per render loops TanStack Table.
Readable surfaces: tables, mobile list rows and standalone content panels use bg-card and text-card-foreground, not a border alone. The shared brand applies tinted, blurred glass when wallpaper is set; only the page canvas is transparent. Keep nested detail tables on their enclosing card or dialog surface instead of adding another glass layer. Standalone inputs, input groups, textareas and select triggers also keep a glass backing; grouped controls stay transparent inside their group so icons, placeholders and values share one readable surface.
Data: TanStack Query over the service API; the API client is typed by hand in src/lib/api.ts (one place per service).
i18n: src/i18n/en.ts is the source of truth, ru.ts is typed by it so a missing key fails the build. Strings through useI18n().t, dates and sizes through useFormat(). Language: saved choice, then the browser.
Sign-in: the panel never shows a login form. No session → redirect to id (OIDC code + PKCE) through the service's /auth/login; @xvii/auth handles it.
pnpm lint and pnpm build pass; the build output is embedded, so a service is rebuilt after panel changes.
