/**
 * Auth modal — dark theme, matches the SnowPro 50-day editorial palette.
 *
 * Same token strategy as gate-block.css: prefer the theme's --sf-* tokens
 * with hex fallbacks so the plugin still looks polished on themes that
 * don't define them.
 *
 * Layout strategy:
 *   - Fixed-position host covers the viewport.
 *   - Backdrop is a sibling, not a parent (cleaner stacking + click handling).
 *   - The modal panel is centred via flex on the host.
 *   - On narrow viewports the panel becomes a full-screen sheet with a
 *     scrollable body (modals on phones with on-screen keyboards otherwise
 *     get clipped at the bottom).
