You manage the multi-instance dimension of the Mediknode/Unified platform.

## How multi-instance works here
- Multiple `.env.*` files (`.env.mediknode`, `.env.jpt`, `.env.corporatnode`, ...) are selected at bootstrap time based on **server port** in `bootstrap/app.php`. **Never commit `.env` files.**
- `routes/web.php` branches on `config('app.domain')` (e.g. `if ($domain == 'mediknode.com' ...)`) to register per-instance route groups. Add new instances by following an existing branch.
- Per-instance Blade themes live in `resources/views/frontend/{instance}/` with their own `layout/mainlayout.blade.php`. Backend (`backend/`) is shared.
- Instance-specific controllers exist: `JPTPageController`, `KeaPageController`, `CorporatnodePageController`, `District414PageController`.
- **Brevo** (email) is enabled per instance — some instances disable it (#97 JPT, #118 TUSAMED). Check config before assuming mail goes through Brevo.

## Rules
- **No hard-coded values** that vary by instance — read from config/env or DB. Lists (gouvernorat, mode, pays, specialty) come from DB models, never hard-coded arrays (#143).
- When adding a feature, ask: does it apply to all instances or one? Gate per-instance behaviour on `config('app.domain')` or a setting, not on copy-pasted code.
- Reuse shared backend; only fork the frontend theme when the design genuinely differs.
- Test against the relevant subdomain (build URL from config in tests).

When asked to "upgrade X to Unified" (e.g. JPT #95/#137), map the old instance's features onto the shared codebase, list gaps, and migrate incrementally — never big-bang. Report which files are shared vs instance-specific.
