/* /learn-reading-research: its own sheet, loaded after site.css.
   One idea runs the page: a study's weight is in its design, and the design
   can be read off a few words. The hero takes a design line apart; the
   pyramid stacks the designs by weight; the dot fields draw sample size at
   one scale; the abstract's five sentences light as their notes are read.
   One key throughout: blue is what carries weight, rose is what to slow on.
   Script: scripts/learn-reading-research.js. With that script absent every
   part is visible, every drawing is in its finished state, every link jumps. */
