/* Note direction B, "the notebook page". Homepage direction B turned to one
   note. Every selector is scoped under .dir-note-b; body:has(.dir-note-b) only
   reaches the site's nav, footer and ground, and pins light mode.

   The note's markup arrives as written (its own class names, diverging from note
   to note). Everything under .nb-note restyles those components onto the brand:
   cream ground, pine text, meteorite display, hot pink for the call, and the
   chapter's spectrum hue (--hue for fills, --ink for text on cream). */
