/* 鮫洲驾驶模拟器 · account pages (/login /reset /admin /records).
   Same house look as the landing (landing/v2/src/tokens.css + base.css + shell.html): dark gauge-face ground,
   road-paint text ladder, lane-blue accent. Served under a strict CSP: this file is the only stylesheet the pages
   own, so no inline styles and no style attributes anywhere in the markup. */
