/* Navicade blog look. Tokens only: no colour is set here that a token does not own.
   Source lives in blog-src/blog.css; build.py copies it to blog/blog.css.
   Bands follow the direction: black head, white reading band, black next step, black footer.
   Spacing comes from the "spacing" tokens in tokens.css: the page starts --sp-page-top under the header, every band
   is --sp-section deep, and the eyebrow (.label) and the next step band are the home page's own rules (page.css, sections/shell.css).
   Type tokens --t-h2x and --dim come from the direction block in tokens.css. */
