/* The demo site's stylesheet. No framework, no build step — the same policy
 * the JS follows, for the same reason.
 *
 * This is the kryptic.sh design system, ported rather than linked. Pulling
 * `https://www.kryptic.sh/assets/css/base.css` would have been DRY-er and is
 * exactly the coupling this site exists to avoid: the demos deploy from their
 * own repo on their own cadence, and a page that renders correctly only while
 * another origin is up is not standalone. Variable names, scale and component
 * classes match the org site so the two read as one family; the accent is
 * `--purple`, the same one www.kryptic.sh/projects/crcbl/ uses.
