/**
 * 標準SIDE形式（2カラム・左サイドバーカード）
 * ラッパーは会計ユニットと同じ bm-sidebar-layout（PCで右端ホバーしてしまえる）。
 * 独自メニューが line-channel-* のままの場合の互換スタイルも残す。
 *
 * 利用手順:
 * 1. CSS は header.php が読む（個別 <link> は不要）
 * 2. .unit_main に style="--unit-color: #06C755;"（任意・未設定時は緑）
 * 3. HTML は CONFIG/parts_v2/standard_side_layout_start.php
 *    → standard_side_navigation.php → standard_side_layout_end.php を require
 * サイドバー幅は --bm-sidebar-width（既定 260px。sidebar_layout.css と共通）
 *
 * @see b_template_unit/index.php
 * @see b_template_unit/templates/STANDARD_SIDE_README.md
