"""
Generate OG images for the per-competitor comparison pages, using the same
editorial template as generate_og_images.py.

Outputs to public/og-{slug}.png (matches the ogImageSlug values in
resources/js/data/competitors.ts so the existing route -> file convention
keeps working — we only switch the extension from .svg to .png in
Marketing/Comparison.tsx).

Usage:
    python3 scripts/branding/generate_competitor_ogs.py
