"""Generate assets/og-card.png — the Open Graph / Twitter share card.
|
|
|
|
The card is a static 1200x630 PNG checked into the repo (regenerating it
|
|
is only needed when the branding text changes). scripts/seo_meta.py
|
|
references it as <site_url>/assets/og-card.png on every page.
|
|
|
|
Fonts are macOS system fonts (Hiragino Sans GB); run this on a Mac.
|
|
PingFang would be preferred but is an on-demand download on modern macOS
|
|
and often absent from /System/Library/Fonts.
