Generate AVIF variants alongside WebP in the image pipeline
AVIF image generation is now supported. Enable with avif = true in [images] config. AVIF variants are generated alongside WebP at all configured widths, with configurable quality via avif_quality (default 70). The post-processing step adds AVIF sources to <picture> elements with the correct type="image/avif" attribute, ordered before WebP for optimal browser selection.
