/* The legal and help pages.
 *
 * Deliberately NOT built on tokens.css or styles.css. Those carry the six
 * household themes and the whole app's component surface, and a household
 * that has picked Notebook should not read its own privacy policy through
 * a theme it can change - these pages have to look the same for everyone,
 * including a person who is signed out, locked out, or reading the link
 * from an email before they have an account at all.
 *
 * Both appearances are here rather than only light: a photophobic person
 * does not stop needing dark mode when they open the terms. Same
 * three-state pattern the rest of the product uses - bare :root for
 * light, prefers-color-scheme for the OS, and nothing stamped on the
 * element because these pages carry no theme toggle.
