/* /booth-guide/ (lib/booth-guide-page.mjs).
 *
 * Styled after the restream booth rather than the rest of the site: it is the
 * booth's own manual, and a newcomer should recognise what they read here when
 * they open the booth. Urbanist at the booth's weights (600, 700, 800; 500 for
 * running text, which the booth has little of), the booth's panel and control
 * tokens for the dark theme, and a light counterpart of the same palette. The
 * amber number badges match the callouts drawn on the screenshots. */
