/*
 * styles.css: the look of the ask page (amendment 49 in docs/decisions.md).
 *
 * Layout: a sticky topbar, a standalone login card and a framed two-column
 * panel. Change the look through the tokens on :root and the light theme
 * block under [data-theme="light"]. The page defaults to dark; shell.js flips
 * data-theme on <html>. Every font is a file under /static/fonts (see OFL.txt
 * there); no request goes to a font host. No importance flag and no colour
 * mixing function: mixed colours are literal values per theme. No animation
 * is gated behind the reduced-motion media query.
