Matthieu MALVACHEandClaude Sonnet 4.5 a4e2fcf81b feat(i18n): Enable instant client-side language switching
Refactored i18n implementation to support seamless language switching
without page reload by pre-loading all translations and using
locale-aware navigation helpers.

Changes:
- Created centralized routing config (i18n/routing.ts) with localePrefix: 'never'
- Added type-safe navigation helpers (i18n/navigation.ts)
- Implemented custom IntlProvider with pre-loaded EN/FR translations
- Updated all pages to use new useRouter from i18n/navigation
- Added language switcher to appearance settings
- Removed URL-based locale routing (no more /en/ or /fr/ prefixes)
- Language preference persisted via Zustand localStorage

Getting Started

# Install dependencies
npm install

# Run development server
npm run dev

Open http://localhost:3000 and connect to your JMAP server.

Configuration

Create a .env.local file:

APP_NAME=Your Webmail
JMAP_SERVER_URL=https://your-jmap-server.com

Runtime vs Build-time Configuration

Variable Type Description
APP_NAME Runtime App name displayed in the UI
JMAP_SERVER_URL Runtime JMAP server URL (required)
NEXT_PUBLIC_APP_NAME Build-time Legacy fallback for app name
NEXT_PUBLIC_JMAP_SERVER_URL Build-time Legacy fallback for server URL

Runtime variables are read at request time, enabling post-build configuration (ideal for Docker).

Build-time variables are baked into the bundle and require a rebuild to change.
