/*
 * Blog stylesheet, 2026-10-22.
 *
 * The blog follows the homepage (rebuilt 2026-10-11 in the Agent Maturity Index style), not
 * synos.css: Inter, the AMI palette with light and dark tokens, pill buttons, the homepage nav and
 * footer. The tokens, buttons, logo and footer rules below are copied from public/index.html and
 * must move with it: change one, change both.
 *
 * What is the blog's own is the reading layer: a 720px text column, 18px body on 1.7, a table that
 * scrolls inside its own box, and a chart drawn from tokens so it themes with the page.
