Designed for GitHub's recommended social-preview size (2:1 aspect, 1280x640).
Same visual system as the post cards and the square hero: dark GitHub-slate
background, JetBrains Mono terminal panel with traffic-light dots, Inter bold
title typography, green accent. Left column carries the repo identity (eyebrow,
title, subtitle with `toolchain` in green, thesis line); right column shows a
condensed 5-stage pipeline log.
For upload at https://github.com/recklessop/ai-workflow-course/settings -> Social
preview (no public REST API exists for this; UI-only).
