/* The founder's toolkit: /tools/, /toolkit/, /runway/, /bottleneck/,
   /off-switch/, /12-days/. The Leader's North Star look (steel blue on navy and
   pale paper); each tool wears its domain colour as the accent. Covers are navy
   with gold, as approved on 2 Nov 2026. Light and dark follow /theme.js;
   without script, the device decides. One screen at a time, 390px wide with
   no sideways scroll, calm under prefers-reduced-motion. */
