the facts of three links
| host | site | title | image |
|---|---|---|---|
| youtube.com | YouTube | [1hr Talk] Intro to Large Language Models | yes |
| paulgraham.com | paulgraham.com | Do Things that Don't Scale | none |
| github.com | GitHub | GitHub - Lulzx/cuda-metal | yes |
Six facts per link, fetched ONCE where the network is (mise unfurl <url>) and shipped as data. A browser cannot read a foreign page (CORS) and a build that fetches on every deploy depends on the other site being up; the card is a pure function of these.
