root e9634f0f0d Paint an asset's name gold while any of its values deviates
The inspector already marked an asset value that differs from its schema
default, but the Assets panel gave no hint, so a changed asset looked
like an untouched one until you opened it.

The rule sits next to the existing objectDeviates as a pure function:
assetDeviates asks whether any marked property differs, markedAssetSchema
says which rows the inspector marks at all. buildAssetSection now builds
its rows from that same list, replacing the behavior/rest split it used
to carry, so the list cannot claim a deviation the inspector then fails
to show.

A behavior's variables are deliberately not in it. Their default is
declared on the variable itself, which means the asset value *is* that
default; counting them would paint the fixture's Mover gold while the
inspector beside it marks nothing.
