/**
 * Total Custom Scrolling Grid – stylesheet.
 *
 * Per-instance height, mobile-height and gap values are applied via CSS
 * custom properties set inline on each .tcsg-wrapper element by the
 * shortcode renderer.
 *
 * No theme overrides: typography and colour are inherited from the active
 * theme. Lightbox uses the theme's body colour for the caption and a
 * neutral overlay; the close button inherits font properties from the body.
