/* The one stylesheet for every BotMaker page.
 *
 * SHARED ON PURPOSE. The organization page and the four project pages (each generated by its own
 * repository's build-repo.sh) link this file, so moving between them does not look like leaving the
 * project, and a change to the look is one edit rather than five copies drifting apart. Same origin
 * for all of them — botmakerdev.github.io — so linking it costs no availability a project page did
 * not already have.
 *
 * It therefore styles BOTH markups: the org page's hero and card grid, and a project page's plain
 * h1 / h2 / pre / footer column. Do not remove a rule because this page does not use it.
