/*
 * B2B Portal styles.
 *
 * Goals:
 *   - Theme-agnostic but visually coherent. The host theme provides the
 *     page chrome; this file styles only elements inside our shortcodes.
 *   - Plain CSS — no preprocessors, no build step (Wedos hosting).
 *   - System font stack so the portal looks native on every OS.
 *
 * Naming: BEM-ish (.b2bp-portal, .b2bp-card, .b2bp-card__title).
