- Replace @tailwind directives with @import 'tailwindcss'
- Move custom theme colors to @theme inline block using CSS variables
- Delete tailwind.config.js (CSS-first config in v4)
- Delete postcss.config.js (Tailwind v4 Vite plugin handles everything)
- Add tailwindStylesheet option to .prettierrc for prettier-plugin-tailwindcss v0.7

- Replace 'path' import with 'node:path' protocol
- Replace __dirname with import.meta.dirname (ESM-native)
- Replace minify: 'esbuild' with minify: true (esbuild deprecated in Vite 8)
- Add @tailwindcss/vite plugin to Vite config

- Update target ES2020 -> ES2024, lib ES2020 -> ES2024
- Remove DOM.Iterable from lib (now included in DOM in TS 6.0)
- Remove deprecated baseUrl option (paths now works without it)
- Add tsconfig.node.json with composite: true for vite/vitest configs
- Add project reference from tsconfig.json to tsconfig.node.json

React Compiler rules introduced in eslint-plugin-react-hooks v7:

- App.tsx: replace setState-in-effect with derived state for 'ready'
- AccountContextMenu.tsx: replace Date.now() in render with useState
  initializer (react-hooks/purity)
- SessionTabs.tsx: convert drag ref reads during render to state
  variables (react-hooks/refs)
- NormalLoginForm.tsx: restructure region-change effect to avoid
  synchronous setState calls (react-hooks/set-state-in-effect)
- QrLoginForm.tsx: add eslint-disable for intentional setState in
  mount effect (react-hooks/set-state-in-effect)
- VerifyForm.tsx: move loadPage function declaration before useEffect
  that references it (react-hooks/immutability)
- use-auth.ts: attach original error as cause when re-throwing
  (preserve-caught-error)

Automatic class reordering by prettier-plugin-tailwindcss v0.7
with Tailwind v4 CSS-first config. No functional changes.

- Change 'tsc -b --noEmit' to 'tsc -b' (--noEmit conflicts with
  composite: true in tsconfig.node.json)
- Add tsconfig.node.json to paths-filter for frontend checks

Ignore tsbuildinfo, vite.config.js, vite.config.d.ts,
vitest.config.js, vitest.config.d.ts generated by tsc -b
with composite project references.

When switching region, the login form now correctly:
1. Clears the account/password fields immediately
2. Reloads the last saved account for the new region

Previously, after the eslint-plugin-react-hooks v7 migration,
the region-change branch skipped loading the new region's saved
account, leaving stale cross-region credentials in the form.
