/**
 * @brief Chestnut Modern, a theme for Dotclear 2
 *
 * Responsive breakpoints. Loaded last (after style.css and the active
 * fixed.css/fluid.css) so its overrides reliably win regardless of which
 * width mode is selected. Two breakpoints:
 *   - 1023px and below ("tablet"): loosen the desktop-only #page width
 *     lock, drop the home grid to 2 columns.
 *   - 767px and below ("mobile"): stack #main/#sidebar, collapse the
 *     home grid to 1 column, switch the header to a normal-flow layout,
 *     and turn the top navigation into a toggleable panel.
 *
 * @package Dotclear
 * @subpackage Theme
