/* KORDAR lab — INSTRUMENT
 *
 * One accent, three text weights, sharp corners, hairlines. Everything that
 * animates is behind html.js and stops at html.still, so the page without
 * JavaScript and the page with prefers-reduced-motion are both complete
 * documents rather than blank ones.
 *
 * Fonts are served from this host. The old sheet pulled three families from
 * fonts.googleapis.com, which is why the CSP had to name two Google domains
 * for one page.
