/*
 * QuickTUI content-page stylesheet (guides / comparisons / landing pages).
 *
 * Self-contained: it re-declares the QT design tokens from index.html's inline
 * <style> (:root + [data-theme] blocks) so content pages match the QT visual
 * system without touching the homepage's inline CSS. Tokens rarely change; if
 * the homepage palette is retuned, mirror the :root/[data-theme] blocks here.
 * Consumed by pages generated via scripts/gen-content.mjs.
