- hooks.server.ts: replace empty stub with multi-origin CSRF guard
- Always allows humorunits.com and dickloads.com (+ www variants)
- ALLOWED_ORIGINS env var for additional origins (staging, preview)
- Dev: localhost:3000/4173/5173 auto-allowed when NODE_ENV != production
or ALLOWED_ORIGINS is unset — no config needed for local dev
- svelte.config.js: disable built-in single-origin CSRF check (we own it now)
trustProxy: true so X-Forwarded-Proto/IP are correct behind nginx-ingress
- login route: derive secure-cookie flag from X-Forwarded-Proto header so
session cookies are marked Secure even when Node sees plain HTTP from ingress
- deployment.yaml: add NODE_ENV=production and explicit ALLOWED_ORIGINS
