/* ==========================================================================
   GDCONF Calendar Block — frontend styles

   Architecture:
   - CSS custom properties scoped to .gdconf-calendar-block
   - Blocksy integration: uses --theme-palette-color-1 for accent
   - Dark mode: :root[data-color-mode*="dark"] (Blocksy Pro) +
                prefers-color-scheme: dark (OS fallback)
   - Layout: CSS container queries for component-level responsiveness
   - Popup:  centered modal on desktop → bottom-sheet on mobile
