/*
 * EchoCAD Material Symbols Helper Classes (Phase 4)
 * -------------------------------------------------
 * Material Symbols is the project-wide icon set. The font is loaded
 * from Google Fonts via includes/shell/header.php. These helper
 * classes make it easy to size icons consistently without writing
 * per-icon font-size rules.
 *
 * Usage:
 *   <span class="material-symbols-outlined ec-icon-md">dashboard</span>
 *   <span class="material-symbols-outlined ec-icon-lg ec-icon-filled">warning</span>
 *
 * Default size when no helper class is present: 20px (medium).
