/*
 * we-design-chrome.css
 *
 * Standardised look-and-feel for the design-mode page chrome:
 *   • Generic icon class (`<svg class="we-icon"><use href="#we-icon-…"/></svg>`)
 *   • Tooltips (`[data-tooltip]` floating chip)
 *   • Keyboard-shortcut help overlay (triggered by `?`)
 *   • A small set of chrome-button utility classes that the existing
 *     left-info-panel / right-info-panel buttons can adopt
 *     incrementally without a structural rewrite.
 *
 * Loaded BEFORE the legacy widget chrome stylesheet (mcw-widgets.css)
 * so its more specific selectors still win when both target the same
 * element.
