+<#
+  kie-image.ps1 - generate hero/OG images via kie.ai (z-image by default).
+  Loads KIE_API_KEY from .env.local at repo root (or $env:KIE_API_KEY).
+  Usage:
+    powershell -File seo-audit-2026-05-27\scripts\kie-image.ps1 -Prompt "..." -OutPath "images/<slug>-hero.png" [-Model z-image] [-Aspect 16:9] [-Resolution 2K]
+  Models: z-image (default, fast), nano-banana-2 (premium fallback), nano-banana-pro.
+  Mechanism: POST /api/v1/jobs/createTask with callBackUrl -> ntfy.sh topic -> poll for result.
+  Note: The old /api/v1/jobs/getTaskDetails polling endpoint no longer exists (API change 2026-05).
+        Results are now delivered via callBackUrl (webhook). This script uses ntfy.sh as a
+        free anonymous webhook receiver since no public server is required.
