/* The legal pages: privacy policy and terms.
 *
 * Loaded after `tokens.css` and `base.css`, and composing their classes rather

 *
 * A legal page is the page a visitor opens when they have already decided they
 * might trust you and want to check. So it is set as a document — a contents
 * column that stays with you, a fixed measure for the prose, real numbered
 * headings that survive being copied into an email, and one table that carries
 * the whole answer to "what do you have on me and for how long".
 *
 * Nothing here needs JavaScript. There is no scroll-spy, because the only
 * honest version of one is a script, and a document that cannot be read with
 * scripting off is not a document.
