A copy keeps a value of its own only in a touched group, so a value
that differs from its main's in an untouched group is lost
propagation. app.common.logic.override-scan runs the sync of every
component a file uses in memory and lists the copy shapes it would
change, with the attributes and groups, or :structure for children
that differ. The size of a text that grows with its content and the
place of a layout child are left out: they are not the main's to
give. Copies of components a predicate names are skipped.
debug.scan_overrides() lists them for the current file in the browser
console, skipping copies of library components changed since the file
last synced with the library.
override-scan-test: a synced copy and an override give nothing; an
untouched difference, in a local or a library copy, is found; a
skipped component is not scanned.
