media-process

Takes classified assets and produces production-ready WebP files:

• Base conversion: WebP quality 85, max 2400px longest side
• Thumbnail: 320x320 center crop
• Variants: hero (1920x1080), gallery (1200x800), social square (1080x1080), social story (1080x1920), social wide (1200x628)

Output is organized by guardian: /data/staging/{guardian}/{variant}/{filename}.webp
