/* aycode.ai/docs: three columns (chapters, article, on this page), built on the tokens in site.css.
 * The base rules up to "the manual" are shared with the feature, radar, changelog and legal pages, which load this
 * file too; everything after it is for the docs alone (.docs-shell) and reads like a printed manual in the new look:
 * the overview opens under the start page's horizon, the chapters list like a contents page, screenshots are prints
 * with a torn edge and a strip of tape, notes are paper slips. New motion runs at 10 frames a second (steps) and
 * stands still under "reduce motion". */
