/* tutorials-newdesign.css
 *
 * Overlays the purple/Instrument Serif design system on top of the unchanged
 * shared style.css for the tutorial library only. Linked AFTER style.css from
 * tutorials.html and every /tutorials/*.html so the cascade wins.
 *
 * Approach mirrors /try.html: redirect the existing CSS tokens (--bg, --text,
 * --signal, --border, etc.) to the new palette so style.css's existing rules
 * pick up the new colors without rewriting them. Component-level overrides
 * use !important where style.css has high-specificity selectors.
