Detailed Description

A texture flowing between filter primitives: the runtime handle holding it and the descriptor it was allocated with.

Both pointers name storage the executing graph's arena owns for the whole execution, so a copy of this value stays usable across further allocations. Two values name the same texture exactly when they compare equal, because the arena gives every texture one handle: identity here is what decides intermediate reuse and color-space caching.

A default-constructed value is empty, which is how a refused allocation or a primitive that could not record is reported to its caller.
