/*
 * Investor Portal — frontend styles (Google Drive inspired).
 * Loaded only on pages that embed the [investor_portal] shortcode.
 *
 * Design language modeled after Google Drive:
 *  - Soft neutral surfaces (#f8fafd) and pill-shaped folder cards.
 *  - Colorful filled folder icons.
 *  - Filter-pill toolbar, section headers, list/grid toggle.
 *  - Full RTL support (matches the current theme's dir=rtl).
 *  - CSS variables so themes can override without touching the plugin.
