/*
 * Banjoe Online design system.
 * Plain CSS, not a Tailwind utility layer - this file is guaranteed to render
 * regardless of what Tailwind's JIT compiler had scanned at the last build
 * (this server has no Node/npm to recompile assets/css/tailwind.css, so any
 * brand-new Tailwind class written into a template would silently do nothing).
 * Dark mode follows the existing html.dark class toggle from theme.js -
 * matching dark-mode.css's own pattern rather than Tailwind's dark: variant.
 * Low Data Mode (html.low-data / body.low-data-active) already strips shadows
 * and animations globally in dark-mode.css; components below inherit that for
 * free since they use the same --shadow-* tokens dark-mode.css already zeroes.
