## Drop-in edge-dim overlay for pause/dialogue dim. §2: presentation.
## The ShaderMaterial (and, for the other two surfaces, its Palette-sourced
## uniforms) is built at runtime in _ready() rather than baked into the .tscn
## (deliberate deviation from spec §5.4's "baked" approach) — keeps Palette the
## single source of truth at the cost of an editor preview; the surface renders
## once the scene runs.
