Light and Darkness

Roles: light-source, shadow, illuminated-area, hidden-area, obstacle-casting-shadow, observer

The interplay between illumination and its absence, where light reveals and darkness conceals. As a source domain, light-and-darkness foregrounds the structural relationship between a visible self and its cast shadow: every object in light necessarily produces a shadow, and the brighter the light, the sharper the shadow. Structurally productive because it encodes the insight that concealment is not separate from revelation but produced by it, that shadows are shaped by the object that casts them, and that moving the light source changes what is visible without changing what exists.
