/* =====================================================================
 * LAYOUT: content-hub-tools
 * An editorial content hub whose core offering is embedded interactive
 * tools. Grammar: one reading spine, narrow long-form column, full-width
 * TOOL SHELVES that interrupt the prose rhythm, tools embeddable inline
 * at reading width. Quiet category strip, serif display, humanist sans
 * body, hairlines + gentle lift, 6px radius.
 *
 * Renderer contract (identical to tool-portal-light / brochure-formal):
 *   - MUST NOT declare --section-* defaults; the renderer appends them
 *     after rendering based on palette luminance.
 *   - Renderer-managed surface classes MUST be surface-coloured here:
 *       .features-section, .services-section, .differentiators-section,
 *       .about-section, .faq-section
 *   - Element rules use var(--section-*, var(--color-*)).
