/**
 * Solutions page (slug "solutions") component styles.
 *
 * The reusable design-system pieces (inner-hero, section-header-cyber,
 * hiw-faq, who-enterprise, assessment-cta, buttons) come from style.css and
 * how-it-works.css. This file only adds the Solutions-specific components:
 *
 *   - the growth-staircase stage selector (.sol-stair / .sol-step)
 *   - department cards with new / carried-over state (.sol-dept)
 *   - the "see it run" loop teaser that sends the visitor to /ai-office/
 *   - the industry-preview grid
 *
 * Enqueued only on is_page( 'solutions' ) (functions.php), after style.css and
 * how-it-works.css. Everything is scoped under .solutions-page so it can never
 * leak onto another template.
 *
 * @package Aigenix
 */

/* ============================================================ Section grounds
 * The page canvas is white (see how-it-works.css). These content sections carry
 * light-on-dark text, so they paint their own dark ground, mirroring the old
 * #workflows / #integrations rule the rewrite replaced. #solutions-cta is still
 * darkened in how-it-works.css; the FAQ deliberately stays on the light canvas. */
