/**
 * SNAPSMACK — Social Profile Dock
 * ss-engine-social-dock.css
 *
 * Floating dock of social profile links styled as independent circles
 * matching the download button aesthetic. Each icon is a 48px dark
 * semi-translucent circle with a subtle border. The whole dock is
 * semi-transparent at idle and reveals fully on hover proximity.
 *
 * 8 position classes: 4 corners + 4 side edges.
 * Side-mounted docks slide off-screen during scroll via JS toggle.
 *
 * CSS custom properties (set inline from PHP):
 *   --dock-bg:       circle background colour (rgba)
 *   --dock-border:   circle border colour (rgba)
 *   --dock-icon:     SVG icon fill/stroke colour
