   Vignelli rationalism. Fellini cinema.
   1930s Florence through stained glass.

   Layer stack:
   1. Video — looping film, very low opacity
   2. Gradient panels — drift slowly, create glass opacity
   3. Canon SVG — the lead came between panels
   4. Content — scrolls over everything

   Typography: Helvetica Neue. One family.
   Drama through scale and weight, not decoration.
   Vignelli's actual typeface. Not our fantasy of it. */
