A site is more than the page you open in a browser.
It needs a feed. It needs metadata. It needs cards that do not look accidental when a link gets shared. These are small surfaces, but they are part of the publishing system.
The feed is the cleanest one. No chrome, no layout, just entries. The card is the opposite: pure presentation, generated at build time so the site still stays static.
Both make the site feel more real. Not bigger. Just reachable from more angles.
