## Summary
- **Dynamic Stripe price resolution**: Replaces hardcoded
`stripe_price_id` env vars with lookup-key-based resolution
(`stripe_lookup_key`). A new `php artisan stripe:sync-prices` command
creates/updates Stripe prices from `config/subscriptions.php`
automatically.
- **Locale-aware currency formatting**: Replaces all
`getCurrencySymbol() + toFixed(2)` patterns with `formatCurrency()`
(backed by `Intl.NumberFormat`) across `welcome.tsx`, `paywall.tsx`,
`billing.tsx`, and `step-create-account.tsx`, so symbol position and
separators are correct for the user's locale (e.g. `3,90 €` in Spanish).
- **EUR defaults and updated plan prices**: Cashier currency defaulted
to EUR, plan prices updated to €7.80/month and €46.80/year, and
`pricing.currency` is now shared as an Inertia prop.
- **Promo/discount cleanup**: Removed all FOUNDER discount mentions and
Discord community links from the paywall, landing pricing section, and
invitation email.
