Before / after behavior

• observed — Modified behavior in .github/banner.sh: The .github/banner.sh script was removed; it rendered the light and dark banner SVGs as 1680×420 PNGs using a pinned Alpine Docker image.
• observed — Modified behavior in .github/social-preview.sh: The .github/social-preview.sh script was deleted; it previously rendered the social-preview SVG to a PNG using a pinned Alpine Docker image.
• observed — Modified behavior in .gitignore: Adds /branding-src/ as an ignored path.
