    Initial commit: PocketBase Docker setup (root & rootless variants)
    
    Add Dockerfiles, Compose stacks, and entrypoints for running PocketBase
    in both root and rootless container configurations, plus .env.example
    documenting version, port, superuser bootstrap, and encryption settings.

+# Port for the root variant (only used with `docker compose --profile root up`)
+PB_PORT_ROOT=8081
+
+# ── Superuser bootstrap ───────────────────────────────────────────────
+# On every start the entrypoint checks whether PB_ADMIN_EMAIL already exists:
+#   • exists     → nothing happens (PB_ADMIN_PASSWORD is ignored/optional)
+#   • missing    → the superuser is created using PB_ADMIN_PASSWORD (required in that case)
+# No defaults. Leave blank to skip bootstrapping entirely.
+PB_ADMIN_EMAIL=
+PB_ADMIN_PASSWORD=
+
+# ── Encryption ────────────────────────────────────────────────────────
+# Encrypts the application settings stored in PocketBase's database.
+# Must be EXACTLY 32 characters. Leave blank to disable.
+# Generate one with:  openssl rand -hex 16
+# Docs: https://pocketbase.io/docs/going-to-production/#enable-settings-encryption
