/**
 * envitron 2026 — References-Page Styles
 *
 * Zwei Sektionen:
 *   1. .references-section  — Logo-Grid (4-Col / 3-Col / 2-Col / 1-Col)
 *   2. .references-trust    — 3 Trust-Cards (Versicherung, Inbetriebnahme, Dashboard)
 *
 * Konvention: section > container > hgroup + section__content
 *
 * Logos sind farbige PNG/JPG-Quellen mit unterschiedlichen Aspect-Ratios
 * (manche breit, manche quadratisch). Wir normalisieren das ueber eine
 * fixe Card-Hoehe und `object-fit: contain`, sodass jedes Logo in einem
 * sauberen Frame zentriert ist.
