Featured image options
Illustration or title card — per post
Every guide and blog post has two featured-image options generated automatically: Option A — a property illustration with a dark title band and the Houseplot mark; Option B — a title card on a theme colour (four variants: deep green, gold, cream, forest), diagonal line styling, a frame and the logo watermark. Set featured_mode: card or illustration in a post's front matter to choose; the chosen one is also exported as the 1200×630 social image.
