/* LFAIT Range Master — shared theme.
 *
 * Before this file every template carried its own <style> block redefining
 * .sidebar and .main, so a layout change meant editing twelve files and the
 * pages drifted apart. Everything visual now lives here; pages keep only the
 * rules unique to them.
 *
 * Dark is the default. Light is opt-in via <html data-theme="light">, set by
 * the toggle in _head.html before first paint so there is no flash.
