/* --- Agents (DESIGN.md § Agents, decided 2026-10-16): /agents, after Railway's
   /agents page (owner: "design it after https://railway.com/agents"): its
   structure in our system. A hero with a tabbed one-command box, a row of text
   marks, the directory of agent cards, a comparison table, a grid of what agents
   can do, and the way in. The guides (/agents/<agent>) are the docs frame
   (docs.css). Only the system's tokens, type scale, hairlines, radii and stamps;
   no shadow, no logo, no new colour. --- */
