   OMNISCIENT WEBSITE · BLOG
   Posts and the blog index, written by tools/blog.mjs from blog/_src/*.md. Tokens, buttons, header and footer come
   from base.css. Product shots inside a post (*.shot.html) keep the home page's styles (home.css), so every rule
   here that styles the article text skips anything inside .bl-shot. Square and framed, no shadows, no gradients.
