GH Social Preview Sample

This oshea plugin generates a clean social preview card displaying "wyatt brege" centered on a ribbon background in a monospace font. The ribbon background is generated from aperiodic tilings following the silver ratio in the blue-green spectrum of the gruvbox color palette.

• Standard OpenGraph preview dimensions (1200x630px)
• Centered, monospace typography
• Minimal styling
• Grub

Location: gh-social-preview/

The plugin automatically renders "wyatt brege" regardless of markdown input content. Edit in the frontmatter to change.

git clone https://github.com/brege/gh-social-preview.git

oshea convert gh-social-preview/example.md --filename card.pdf -o .

This generates a PDF card with dimensions 1200x630px using the blue and green color palette.

After generating the card, convert it to PNG and extract the center 30%:
