Tips for a good social card

Title should fit on 1–3 lines. Aim for 6–10 words; longer titles get ellipsised at the end.
Subtitle is the supporting sentence. Two short lines beat one long one.
Author and site are optional. Both render as a small byline at the bottom.
Theme is painted into the PNG, so the same image shows up on any platform (no SVG / no font issues).
The canvas is rasterised at the canonical 1200×630; the preview on this page is shown at half size to fit the layout.
