/*
 * Inniti Knowledge Center — shared "ikc-*" article design system.
 * Used by every knowledge-center/{category}/{slug}.php guide. Uses the site's
 * existing global theme (style.css) + Bootstrap grid; this file only adds the
 * long-form-article layer on top (hero banners, TOC, callout boxes, tables,
 * flow diagrams, FAQ width, related-guide cards, etc).
 *
 * Two co-existing patterns live here on purpose — pick whichever fits a given
 * guide, they are not meant to be mixed on the same page:
 *   - "Boxed" pattern   (.ikc-wrap, .ikc-toc, .ikc-quick-answer/.ikc-insight/
 *                        .ikc-framework/.ikc-cta, .ikc-flow)         — used by
 *                        diesel-consumption-vs-equipment-utilization.php
 *   - "Sidebar" pattern (.ikc-wrap-wide, .ikc-hero-banner, .ikc-layout +
 *                        .ikc-toc-side, .ikc-erp-flow, .ikc-type-grid,
 *                        .ikc-kpi, .ikc-action-steps, .ikc-cta-bar) — used by
 *                        equipment-idle-time-in-construction.php
 * Shared by both: page/typography base, blockquote fix, .ikc-formula,
 * .ikc-table(-wrap), .faq-accordion width, .ikc-related(-card).
 *
 * Per-page background photos (e.g. the hero banner image) are NOT set here —
 * this file only defines the gradient overlay; each page adds its own photo
 * via a full inline style="background-image:linear-gradient(...),url(...)"
 * on the .ikc-hero-banner element (see the rule below for why — a CSS custom
 * property will NOT work for this), so this file stays image-agnostic.
