"""An image is not a cross-reference, and a carried image is counted (0.10.0).

Two door-level properties that the asset layer would otherwise get wrong in
opposite directions.

**A markdown image is not a pointer to another concept.** `structure._LINK`
reads `[...](target)` and does not care what stands in front of the bracket, so
every pointer this capability writes would arrive in the index as a `references`
edge to a concept that cannot exist. That is the same defect K3-21 hit when the
`Enclosing section:` line was read as body text and became a second, unresolved
edge; the repair there was to append after derivation, and the repair here is
that an image link is a different construct from a link.

**A concept says how many images it carries.** A bundle that holds an image and
says nothing about it is only half an improvement: the count is what lets a
consumer, or `okf quality`, tell "this document had no figures" from "this
build dropped them". The key is CONDITIONAL -- written only where the count is
non-zero -- so a bundle of documents without images is byte-identical to one
built before this existed.
