   Design notes
   - Paper white page, near-black ink: long reads are easier on light.
     Black is kept for "screens" only: the hero frame and the diagrams,
     which sit in dark monitor panels like a camera display.
   - Glass: translucent white panels with a lit rim and a soft cool shadow.
     Soft light leaks in the category colours sit behind the page, so the
     glass always has colour to blur and never reads as flat grey.
   - Category colours come from the false-colour exposure scale used on set
     monitors. They only ever mean "category", never decoration.
   - Type: The Bold Font for titles, Futura for every text. Futura is a paid
     face, so it is used where installed (all Apple devices) and Jost, a
     free Futura revival, is served to everyone else.
   - Articles are built for reading: 66ch measure, justified text with
     hyphenation, generous rhythm, the summary right after the intro.
