fix(proxy): keep admin login and assets working on plain-HTTP hosts

The /admin guard always read the `__Secure-` session cookie, but Auth.js
only uses that name when AUTH_URL (or the request) is HTTPS. With an
http:// AUTH_URL a signed-in admin was bounced between /admin and /login
until the browser threw "too many history calls". The guard now picks the
cookie name the same way Auth.js does.

The CSP also sent `upgrade-insecure-requests` to plain-HTTP visitors, so
the browser rewrote same-origin fonts/scripts to https:// where nothing
listens. It is now only sent when the visitor reached us over HTTPS.

 ### 2. Database Setup
 
-The CMS shares a database with the Polaris/Arcturus emulator. Use an existing database or create a new one:
+The CMS supports both **MySQL / MariaDB** and **PostgreSQL**. The database type is automatically detected from your `DATABASE_URL` protocol (`mysql://` or `postgres://`).
 
+#### Option A: MySQL / MariaDB
+
+Create your database:
 ```sql
 CREATE DATABASE IF NOT EXISTS epicnext_cms CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
 ```
 
-The CMS reads emulator-owned tables (`users`, `items`, `rooms`, `bans`, etc.) directly. It never creates, alters, or drops them. The Drizzle schema in `src/db/schema.ts` is generated from the existing database structure and does not modify it.
+#### Option B: PostgreSQL
+
+Create your database:
+```sql
+CREATE DATABASE epicnext_cms;
+```
+
+The CMS reads emulator-owned tables (`users`, `items`, `rooms`, `bans`, etc.) directly. It never creates, alters, or drops them. The Drizzle schema in `src/db/schema.ts` maps to the existing database structure.
 
 > **Note:** The CMS does **not** own the emulator schema — it maps to those tables via Drizzle. Never run `drizzle-kit push` / `migrate` against the shared DB. CMS-owned tables (`website_*`, `radio_*`, etc.) are created via idempotent SQL in `drizzle/migrations/`.
 
+#### Multi-Engine Architecture & Dialect Routing
+
+EpicNext-CMS features a robust, multi-dialect database abstraction layer powered by **Drizzle ORM**. Depending on the connection string protocol supplied in `DATABASE_URL`:
+- **MySQL / MariaDB (`mysql://`)**: Utilizes `mysql2/promise` connection pooling with optimized keep-alive, named placeholders, and strict statement hardening.
+- **PostgreSQL (`postgres://` / `postgresql://`)**: Utilizes `node-postgres` (`pg.Pool`) with high-performance async client handling.
+
+The query builder and helper functions (`queryRows`, `execResult`, `affectedRows`) automatically normalize driver-specific responses (`ResultSetHeader` vs PostgreSQL result objects), ensuring seamless compatibility across database engines without application-layer changes.
+
 ### 3. Configure Environment

 ```bash

+## Production Deployment & Zero-Downtime Releases
+
+EpicNext-CMS is engineered for enterprise-grade production environments with zero-downtime deployment capabilities:
+1. **Blue/Green Slot Deployments**:
+   - Updates run through containerized slot orchestration (`scripts/docker-update.sh`), ensuring seamless transitions between release versions without dropping requests.
+   - Automatic health check verification (`/api/health`) validates database connectivity, Redis/Valkey status, and RCON liveness before routing production traffic.
+
+2. **Automated Rollback Protection**:
+   - If a post-cutover health check or startup sequence fails, the system automatically triggers a rollback to the previous stable container image and logs the incident.
+
+3. **High-Performance Caching & Rate Limiting**:
+   - Integrates with Redis / Valkey for distributed session storage, global rate limiting, and ephemeral response caching.
+   - Multi-tier anti-DDoS proxy filtering defends against volumetric application-layer abuse with automatic Cloudflare edge-block mirroring.
