/* The RIDE Forecast. Visual canon, PRD §11.

   Lineage: Swiss International Typographic Style, Gerstner's Designing Programmes.
   You design the system that generates outputs, not the one-off. Hard grid,
   restraint, one accent at a time, regime colour used only as data.

   Temperature: this is the product layer, one degree warmer than the science
   layer. Warmer paper, more air, the copy carries the heat while the diagrams
   stay strict. */
